I think it might be even opposite. Springs can save energy.

I really like the Team Pro that is on my Lemond but I've been thinking of trying out a Swift just because....

I have a mtb that I use on mup and not a ton of pounding. crushed limestone, cinder, dirt, paved and loose stone. I have swapped out seats and am still having problems. any specific model you guys would suggest? single spring like the champion flyer or b67? I am also considering adding aero bars for a more comfortable position on those 50+ mile rides when I hit a lot of paved areas.

I wonder if heavier riders added pressure on the seat, is a bonus. Does this help with breaking it in? hmmm...

I just shifted my B17 to my MTB and put a Team Pro on my roadie. I have discovered that it is not the saddle that breaks in - it is my butt ;) The team pro was comfortable out of the box, however, the positioning is a bit different, so that will take a little dialing in.
