Thanks for the excellent feedback, all. Best question award goes to thechamp "So you've cracked two lightweight mavic rims and are thinking about getting a third?"
Thanks, Air for all the great cross-threads. No pun intended.
I'm leaning towards the Deep-V's, although I'm probably going to have get valve extenders for my Slime tubes. They only come in 48 mm as far as I know. Any of you have to use valve extenders with the Deep Vs?
Also, after reading Sheldon Brown's post on another thread, it looks like I'm back to the drawing board on the hubs. I very much like good sealed bearings, but since I'm averaging 10,000+ miles per year in all kinds of weather, I need something that's servicable. I was originally going to go with Phil Woods, but their bearings are press-fit into the hubs and don't seem very servicable to me. Maybe they wouldn't need it for a long, long time.
