So he's not buying this frame off you then?
I've had two very very similar bikes - one with s-bend and one with single bend - and I think I actually prefer single bend. I'm big enough to say I don't know why....I think they might have more predictable or linear flex/resonance characteristics, but I'm not a Physicist or Metalurgist so don't quote my seat-of-the-pants report.
Still, probably the biggest reason to use s-bend chainstays is heel clearance if you're a 'heel-in' kinda guy, but honestly, I don't think it really matters which one you choose. If the guy had said "Coz they look cool and that's what Columbus is selling" I'd go "right on", but....vibration damping? I don't think so. You want vibration damping? Get a full suspension bike or take 2psi out of your tires. Both would result in more 'vibration damping' than s-bend seat stays IMHO.
