I was lucky to a friend who raced for the past 30 years, and collected many many saddles. I took a box full from him and started to test ride them. One saddle i came back to all the time was the
Avocet Air O2. It is not the most durable saddle, but man, fits my a$$ like a.... what ever fit an a$$ best..

and I see that they have it now with Kevlar reenforced corners, which will fix the durability issue.. It sells for ~$80.00
