I rode a 155 Power Expert for a couple of years. I went through 8 saddles before I found the Power saddle. I rode a 140 mile ride on the Power saddle last summer and it was comfortable all day. I got that saddle torn up in an accident. I strayed and tried other saddles. I'm back on a Power Pro Elaston. The marketing guys at Specialized say that sitting on Elaston is like "sitting on a 1,000 pillows". I'm not sure about that, but it is comfortable so far and the padding feels great on the sit bones. I am doing a 75 mile ride with 5600 feet of climbing on April 6th. That will be the real test of how the Elaston does on long distances. I have mine level on the first 2/3rd of the saddle so you can push back against the tail on hills. Good luck with your Power Comp, I hope you find the Power saddles as comfortable as I do.
