I now have well over 2000 miles on mine. Including 5 days of Bike Virginia with up to 65 miles of significant hills on some days. I also commute 25 miles round trip about 3 days a week.
I am very happy with the saddle and currently have no plans to change it. As I posted before I did need to fiddle about quite a bit to get it right.
The only strange thing I notice is that around the 10th mile I start feeling a little discomfort for about 3 or 4 miles, then it settles down and I finish 50 -60 miles with no problems.
