Not for me. I'm already a pretty emaciated old fish. Actually these, what my sister calls, "serving spoon" saddles suit me pretty well. At 155 and only 6' tall my butt is not hard on a seat. I have actual Vetta Tri-shocks on my Trek ZX7000 and my Cannondale R600 CAAD3. I can do metric centuries at least and all the recreational riding I wanna. Brooks saddles are not high enough on the need/wish list yet.

I'll keep your crankset recommendations in the bike's file folder. For now the Suginio VT bits will keep the thing going down the road.
