Hmm, I'm guessing you don't hear much from the ones that haven't sold theirs.
I put 12,500 miles on the stock 2010 seat before switching to the Kawi Low Gel seat My only real motivation was to try a lower seat.
I put 3,500 miles on the Gel seat, all the while thinking it was too hard, but it would "break in". Finally after a long 3 day riding weekend, I couldn't take it anymore, and switched back to the stock seat I thought was just fine, only to find out after 4 more days of riding that it was now too soft to get comfortable on.
Now I'm back on the Gel, and it doesn't seem quite so bad, but I really think I'm stuck somewhere in between, wondering "What have I done?? I ruined a perfectly comfortable stock seat!!"
