I just got a Serfas women's tri saddle. Different seat post to put me in an "aero" position during the tri, give me more power in the running muscles when I come off the bike.

I'd switched from a Terry CrMo to a Serfas saddle and was happy with it on my Bianchi Veloche. 12 mile ride yesterday with the new Serfas tri saddle, and I was shifting around the whole time to relieve pressure on soft tissue, today pretty sore over the sit bones.

Anyone else with tri saddle experiences/suggestions to share? How important is a tri-specific saddle when riding in the aero bars?
