I went with the M28 aeros. They are great! In my opinion very compariable to the Ksyrium Elites. Same weight, bladed spokes, and I believe stiffer (cant even flex the spokes with my hand) very durable! Like that out of the box. Got mine for $300 with shipping @ a show. I almost went with Mike Garcia's, seem to be lighter and built to your liking, but more expensive. Both seem to get great review everywhere.
