I used to use the 2 pin cup, until I swithched to the North XT extension (which is an outstanding piece of design now that they have ironed out the bugs) This requires the euro pin system.
I broke 2, (2 piece, sheared off, as described above) had long swims back in.
I now carry a spare euro uni attached to the back of my harness in case of emergency,
....but I've never needed it (touch wood) 'cos I also switched to the Chinook 1 piece machined pin and I also have a North 1 piece pin.
I agree with Mark about the 2 pins getting sloppy as the holes go out of round, and the plastic wears. (probably doesn't effect its performance, but it just feels dodgy)
Euro pin for me but only the Single piece machined ones, there a few around now. Ive sheared off a couple of the older threaded types. But the threaded pin types can vary in thread size, some brands are 8mm and some are 10mm which can make a big difference. Anyway I stick with the machine types 12mm pin for the amount of sailing i do. But you do need to change the tendens at lest once a year maybe twice for me .
Although the string on a tendon base can help with multiple failures, where the webbing with a boge joint only helps if the top and bottom of the joint are still intact.
With a tendon you can shear the tendon in the middle or at either end, have failure of the bolt that attaches the tendon and also partial failure of the cup that the pin or base plate attach to and the rope will still help you get back in.
With a boge and webbing, dimply due to where it all connects, pretty much anything other than the joint shearing through the middle will mean a loss of rig connection.
To those of you who like the cup style, how do you get the bolts undone without having to find a stick or screwdriver to depress the bolts? I can never do it with just my fingers. Chinook europin for me.
They're blokes...I couldnt either which is why I bought the other system. I think I had a 2nd hand version with the pins and just couldn't undo it, had to get a bloke with strong hands to undo it.. Windsurfing isn't set up for females with tiny hands..I cant depress the clips on the new waist harness's either [}:)] that's why Ive stuck with my old one..
which one do you use ? which one should i look at getting ?

once people start trying tricks or sailing in waves (or anything that causes them to crash a lot), they quickly begin to appreciate the benefit of the above model over the others.
If you are mowing the lawn, you'll most likely be okay with any of them
i noticed in the geraldton shops and beaches, this is all that is sold and used
I did broke two tendoms in euro base this season so mybe is the right time to convert to US two bolts system When I did last switch years ago in oposite direction I was thinking that now I am changing old fashioned technology and gear to new modern staff.
Beside the safety tape looks stronger that two thin ropes that broke all together with tendon recently -then sailing back with two separate pieces is real hassle.

Haircut, I'd be very interested if you'd care to elaborate onthis. The advantages of this type of uj aren't clear to me. (also love to know what "mowing the lawn" means!)
Stuff breaks because it's old or damaged, just look after it and you'll be ok. I've replaced my tendon every year for the past five and have not had a problem. Just pick one and go sailing, This is looking like one of those threads that will never die....Do I seriously need to mention "powerband" again?
William, just pick one or the other buddy and you'll be fine.
Powerband. Where do I score on them from? I feel the need for speed.
I have one for sale, I have proof of purchase to prove that it's the real deal not one of the fake ones you get off the net. Trust me.....I've pulled off every forward, backloop, spock and every other trick I've tried from the moment I've put it on. $300 and it's yours....do I need to mention that Gollito wears one(I don't actually know this for a fact but he has something going for him)
I accept PayPal or direct deposit, just supply me with you account and pin numbers and I'll send it to you straight away without delay, I'll even insure it for you at no extra charge.
When mine pin went the first time i was still harnessed into the sail and the board was unfetchable in high wind i shartbaited it to the beach (1.5 hours) holding onto the boom and sail. (amazing what you try and do with that so far out). Second time the pin failed i managed to recover both items and used the emergency down-haul rope to wrap around the bottom of the u/j By the time i got back to shore the extension had put a 2 inch hole thru my board.
If your going out far from experience id use the cup! For me it eliminates a another element of catastrophic gear breakage thus could result in big swim.
The down side the to cup is the universal seems to go oval shape and bend To me this is a sign of fatigue and then it will require replacing.
Also the rubber grommets should be replaced each year Its a simple operation that requires (metric) hahaha 'allen keys socket set and high strength locktite. Make sure when servicing tendons you locktite the locknut and leave at least a .2 clearence on swivel.
I have posted picture of the problem previously and servicing on u/j joints but can locate the thread !
7.9mm 316 stainless round bar can take a average maximum (lift)force of 3 tonne to split. This is greatly reduced by constant dynamic (shock)loading. If there is no radius on the critical sheer point you can half it.
^^ the point is that if the pin is screwed to the cup that the tendon sits in, the screw can shear off. The screw is about 6mm and has work hardening and machine cut threadss so it is a lot weaker than a bit of 8mm stainless. I think you have broken 2 piece units.
In the Chinook and some others the pin and cup are machined from one piece of billet which makes it considerably stronger. Look at ikw777's pic - in the single piece europin's liek Chinook, that red line does not show where 2 pieces join - above and below the red line is one chunk of metal.
Like vando asks - has anyone broken a single piece europin? I have never heard of one

Breaking tendons has nothing to do with the type of attachment used... us base or euro pin can use and break tendons.
Don't get the two peice eu pin cause I snapped about 4 in a row, gotta make sure you get the chinook or north or what other machined eu pins, the other crappy one are for beginners gear only, cause you will break them
I've been happy with eu pin with the tenden great bit of gear,
I had a look at a few guys base , and notice every one had the double pin on the bottom
i like the idea of the quick lock and you can take it off to travel
thinking of getting some thing like this.
If you are going to use a tendon, at least get one with the safety system being downhaul rope. That webbing obscures the view of the tendon so you will not easily see if it starts to crack. Plus how is it attached? Can you see if it is frayed at the very end inside the assembly? A simple bit of rope with a knot in the end is strong, visual, easily replaced.
I really dont understand 2 bolt bases. They were fine in dayes of olde but so many modern boards need the mast base at the extremities of the mast track - you can't just stick it in the middle and hope for the best. The single bolt one that you slide in the mast track and spin to tighten up has never ever slid on me, no tools needed and I have way more adjustment. What's not to like....
Haircut, I'd be very interested if you'd care to elaborate onthis. The advantages of this type of uj aren't clear to me. (also love to know what "mowing the lawn" means!)
they seem to last, are simple design, and easy to adjust mast track position . for me they certainly outlast any of the eurpin and cylindrical tendon combos i've had in the past. i'm currently breaking 4 booms to 1 chinook tendon/cup base. the bases last me about 2-3 years, and then i replace with new and keep the old for a spare

Thanks, I use the same patten and brand, but with the tendon. I replace the tendon each September. They always look in perfect condition but I replace them anyway. It's only 30 bucks. I replace the entire assembly every 3-4 years (only done it once).

has anyone actually Broke a single piece euro pin.
