Everyone is different when it comes to saddles. I spent the last two years riding the Specialized Power saddle. It has a short nose and super comfy on long rides. I have 130 sit bones measurements and the 155 saddle was great. I got my power saddle torn up in a crash. I tried the Power Arc saddle, it was comfortable, but I got the Holographic reflective saddle and the material is too slippery. I then tried the Pro Stealth Saddle in a 152. It is a nice saddle and I experimented and found 3 degrees nose down to be the most comfortable. It fits a lot like the Power saddle, but doesn't have the kick up in the back.
Here is a good review of the Pro Stealth saddle.
