Which one rides the best out of everything you’ve tried? Are the differences in ride performance that drastic between the top brands?
I really like the Signature gear, especially the Stealth 175. It's really user friendly and will go as far as you want to push it, it'll work in all conditions.
The Signature stuff doesn't really have that "built-in lift" of other brands though, so it can be a drawback if the waves are really slow or small.
I don't think the ride performance is drastic between brands, but their are definitely quirks from brand to brand. MFC is twitchy, Signature doesn't lift quickly, Naish is heavy, etc.
A friend of mine rides Armstrong gear, I tried it once. Really good stuff and he never talks about changing foils. He’s a pretty big gear hound too, will decide he doesn’t like something after one try.
