I have had:
Chinook Alu (overall quite good)
Chinook Carbon (broke 1)
Neilpryde X5 (bend 1)
Arrows alu (still working/ oldest)
But I have the best extension right now:
Neilpryde MXT X6 48cm
I use it on NP RSRacing and don't need a rigwinch
You get standard a dynama rope
And together with NP Powerbase it works great
I am a speedsurfer and have a lot of 40kn offshore @ sea, and the foot/base are really tight. I feel really confident, and the sails power is directly on the board
