I think the MF's are a bit over rated. I have a pair of 404 FC tubulars and prefer the ride to those more than the MF's. They are way sketch when its windy out. Check out the new Boyd's wheels. They have moved to a wider profile this year. For the price...its not bad. If using them for racing only...I'd go for the tubulars. Unless you're racing Kona...I'd go all the way with 90mm front and rear. http://www.boydcycling.com/carbon-tubulars/ You can always go Zipp...can't go wrong with them. They hold their value pretty well too.
