I love my SI Lady Gel Flo also...however, I have developed a mean saddle sore right on the crease between my leg and crotch area on the left side. It's probably related to the way I sit on the saddle since my accident in '05 in which I fractured both the bones on the lower right side of my pelvis (pubic rami and ...?) I can't blame the saddle; it's really comfy, supports my sit bones perfectly, and so long as I pay attention while riding, I can keep the saddle sore from bothering me too much. But I really do want it to GO AWAY.

Glad it's working for you! 60 miles is indeed a good test!
