Here is my opinion of the Avenir Big and fluffy saddle I ordered http://www.amazon.com/Avenir-Mens-Comfy-Saddle-Black/dp/B00165Q4MQ/ref=sr_1_3?s=cycling&ie=UTF8&qid=1308098423&sr=1-3
It's made by marketers. When you first look at it, you think, "It's two 4 inches of fluff. It can't NOT be uncomfortable." And when you first sit on it is indeed comfy. However, once you start to pedal you notice that everything is wrong; the damn thing is to big, and every time you push down with your leg the inside and back of your thigh digs into the seat. This causes the rider to move forward to where the saddle is thinner so that they can pedal more comfortably. But then you're sitting on the edge of your seat and you lose the lateral control you have when your legs are wrapped around the saddles nose.
That being said, if you don't pedal, it's pretty comfortable. But only for short rides. Longer than thirty minutes you start to notice that the gel which is supposed to provide cushion instead spreads the load of your body to non weight bearing tissue and muscle in your legs and ass. This cuts off circulation and causes numbness and soreness.
Also... the thickness of the saddle is a problem. It requires lowering of the seat post, which is just one more way it messes with the seating geometry.
So.... I still haven't found what I'm looking for. Oh well.... these things take time.
