Thanks one and all for the sound advice. I don't get the luxury of riding more than 2 - 3 times a week. And longer rides are done on the weekend. Running your own company keeps one rather busy (even though my friends swear I don't get up till 10am! ). Before I make any drastic changes, I'll continue to ride and see if my rear end doesn't get accustomed to the ride. I will say, when researching my Madone, the one consistent negative issue was the saddle. In time, that might be the biggest change I make if I don't find "butt happiness" by the end of the summer.
Again, thanks for the great replies.
