OP, if one of your Bonty wheels is a twin-spoke model and the other isn't, I would have an immediate opinion as to how your bike came to have two different wheels.

But that's neither here nor there. I would not mess with tubulars. I would, however, put these on the short list: http://www.competitivecyclist.com/pr...258.622.0.html

Problem is, that limits you to 3 tires, all made by Hutchinson. (Intensive = mileage, Fusion = all-arounder, Atom = race slick.) But I doubt you'll find a solution that gives you fewer flats, and less total wheel & tire weight for under $1000.
