I noticed that Fizik categorizes its saddles as meant for most flexible ("snake"), intermediate ("chameleon"), and least flexible ("bull") riders. I noticed this after picking up a $30 used Fizik saddle. Turns out it is one of the "meant for snake" models. So I am wondering: how would your flexibility influence the optimal saddle shape? Does it have something to do with what party if your pelvis is assumed to be contacting the saddle? I'm also wondering what sort of animal I am.
