Actually, a good saddle fitter can fix some fit problems with custom padding... the saddle guy here carved and made custom pads to fill where Bay had voids.
They can't fix a saddle that is too narrow for him, and a saddle that is too narrow would sit too high and might give you that rolling sensation. If the tree is too narrow, more, thicker padding would make it worse. It could be that a thinner, but fitted pad, would work better than the bulky one, and a good saddle fitter would know. Taking him in, and your gear, is the answer. Bay's custom pads and his work on them cost about $150, if I recall.
I'm going to reply to this post and see if that speeds up it's posting. :~D
I was wondering if they could do something like that to fix it. The pad I had, the old one use to be bulky:), but it had packed down. Maybe that is why it worked better. It's hard to imaging it's to narrow for him. Belle and Rusty seem wider that he is.
The saddle shop I would go to is the one that built the saddle. They are very knowledgeable. That's where I bought the new pads, maybe if I need something different they'll exchange~crossing fingers~:)
