Butt-cheek chafing = too-wide saddle?

[zoom-zoom]

That sounds like a pretty classic case of chafing from a saddle that is too pear shaped for your particular anatomy.

As your hip joint flexes and extends the pear-shaped transition from "sit" to "nose" gets in the way and rubs.

Usually chafing in the creases where the butt meets the leg.

Ok, shape was my 2nd suspicion after reading around. And my saddle does seem fairly pear-shaped. Does this mean I likely need the t-shaped sort of saddle? Any suggestions on models that would also have a cut-out? I've been curious about the Specialized Jett or Selle Italia SLK--would either of these likely serve me better than my current saddle?
