Well, I ordered a two-way fit wheelset today (primarily just to have a better all-around wheelset) so I'll be giving tubeless a shot. I've not found tire costs to be too bad--got some Atoms for $54 each including shipping.

What should I get for patching up the tires? This stuff? This?

I might try some of this Caffe Latex stuff for flat-proofing goo: http://twentynineinches.com/2009/04/...-latex-update/

It requires less than 50 grams per tire, which sounds pretty good for not having to worry about road debris. How much weight does the Hutchinson Fast Air add to a wheel?
