I've been foiling for just over 9 months. I started off with the LOL 1300 in Nov 2020 with the full carbon mast. I switched to the Takuma Kujira 980 in Feb 2021. I got the Kujira 1210 in late May 2021. Since then, I've been switching off between the 980 and 1210. Since I started, I've been averaging 5 or 6 session per week.
Possibly due to my weight at 140 lb (63.5 kg), I have NOT had any problems with the front wings getting loose. With the 980, it fits assembled in my hatchback, so I never disassemble the wing unless I switch to 1210.
The stock rear wing had a tendency to get loose, until I switched to a slightly shorter screw. Now, when I use the stock rear wing, it never gets loose. However, I mainly use the KDMaui 13.5" tail wing (which also never gets loose).
I've hit cobblestones on multiple occasions with both front and rear wings. All my wings are very scratched up, but still watertight. I've been very pleased with how the durable the Takuma wings have been.
I bought the 1210 because after 6 months of foiling, I had only gotten one double dip with the 980. I wanted to see if the 1210 could up my pump game.
I wear a Garmin Fenix watch to track my waves. With the 980, after kicking out, my longest pump out the back was 69 yards. With the 1210 my longest pump out the back was 80 yards.
At first, I was highly disappointed that I didn't immediately double my pump distance. But then, I was noticing with the 1210, my "long" pumps were happening more consistently and if I kicked out without much speed, it was much easier to pump up to speed. Double dips happen a lot more often on the 1210.
At 9 months of foiling, I've been able to increase my max pump out the back from 80 to 120 yd with the 1210.I actually prefer to ride the 1210 over the 980 because of the longer pumps.
I switch to the 980 when the surf gets CH+ or a lot of back wash. Takeoffs are much easier with the 980 once it gets CH. I also just seem to fall less with the 980 if its choppy/backwashy.
With regards to turning, the two wings feel about the same to me. However, I'm only doing big cutbacks. Once I start doing wraparound cutbacks, I'll probably notice a bigger difference.
I ride both wings with 2x Takuma baseplate shims, all the way back in the tracks on a JS 4'8" (31L). Here's a Surfline rewind with me on the 980. I hit the sandbar at the end.
