If youre looking for an all around cable board I personally wouldn't recommend full flex unless you plan on exclusively hitting rails.
From personal experience the easiest to learn on, most versatile boards at cable Ive seen so far in no particular order
Byerely Conspiracy/Assault - more of an acquired taste but still sick
If you like flex I think the LF hybrid is the best solution for a more versatile board at cable. Havent tried the CWB vibe but it looks interesting.
I actually hate the clash but I love Nick D's riding so go figure, but asides from a period of interest when it was first announced as Nicks pro model I believe it is not that popular anymore.
