Hey Andy,
There are quite a few guys that can hook you up with gear around the sandgate area.
Kitepower at clontaff,Surf Connect at sandgate & Briskites at Brighton.
All these guys operate at Sandgate and all coach as well as sell their recommended brand.
This worked for me as well as talking to the local lads as they set up and pulled down gear.
15-25nts is what you can expect most days depending on the season of course.
Last sunday there was nothing all morning then like somone flicked a switch 15-20nt came blowing in.
Hope this helps
Richard
PM me if you want my decission I wont bag any of the guys they are all very professional,my decission was based on who I thought would look after me in the years to come that this new hobbie will take from me
