Yeah this narrow twist crap drives me insane too. Had a saddle fitter telling me that I need a narrow twist saddle with thigh blocks. I thought to myself "wow so I can had a bruised crotch AND dislocated hips, right?". Just because I'm a 5'3" woman does not mean I need a narrow twist! I ride in a "mans" saddle (endorsed by Jan Ebeling) but all those narrow twist things leave me not being able to walk. I like a normal twist and a wide seat, gives me so much more stability in the saddle than any thigh blocks or a huge cantle ever could!!
