My friend's 9thwards broke twice. Idk what happened the 1st time, but they send him new ones, he landed on his back in pow trying a backflip and the tails looked like Hellbents
don't hold me to this, but i hear that the comptes have a stiffish flex
ar6s are pretty flexy, very, very smooth flex, but for example the pipe cleaners have a bit more snap. it all depends what kind of feel you're looking for.
