Sitting too far back on Specialized saddles?

[bluebug32]

Have you seen the discussion about the Romin under the Most Hated Saddles thread?

I'm 125 center to center, and used a 143 Toupe initallly, then developed problems. Went to a local bike shop and sat on a 143 Phenom, and the guy pointed out that I was sitting too far back. Now I have a 155 Ruby and 155 Toupe. Perfect for me.

What are you center to center? According to the chart, I fall between those two sizes.

Huge difference for me.

I can't remember the exact sit bone measurement he said. I'll have to measure them myself, though I have no playdough!

The Ruby is slightly plusher than the Toupe, correct?
