I have B-17s on two of my bikes and a B-66 on another. I really like them and felt they were very comfortable from the first ride. I can't imagine using anything else at this point. I have always read that they were extremely comfortable, but I'm...well, I'm frugal...and I didn't want to put out the cash for one. Now, I have three (even though I traded a friend a set of Brooks grips that I had $25 in for the brand new B-66).
