Thanks for the advice about the seat. I think I'll try the seat cover as a first option and see how that goes. I did take the MSF class...in the rain for the entire weekend. We were having a nice nor'easter on the weekend I had my class, so that was a nice learning experience. Believe me, I was a bit nervous when getting on the Rocket at first. It was the best fitting bike for my size (6'6", 270lbs). So it didn't take too long to get comfortable on it.
Once again, thanks for the advice about the seats.
