Hrmmm...so I think I'm running into the 155 Ruby being maybe not quite t-shaped enough. The transition of the 155 Ruby vs. the 143 in the Jett make them look pretty dissimilar. It's not so bad when I'm on the hoods, but in the drops I am definitely feeling sorta tender in that zone where my inner butt-cheek meets the back of my thigh.

So I think I'm back to considering the SSM Glamour Arrowhead or SI Turbomatic...*sigh* Which one was softer/firmer of the two?
