I don't generally race the deep-v's - they are little on the heavy side for the type of racing that I do.(that and my rain bike is a 650 wheel bike and my race bike is a 700 so not interchangable..) Aerohead's are really nice too - lighter than the Deep-V's, my husband has a pair of them that were hand built for his track bike. (they also come in really nifty colors - as do the deep V's as long as you are riding 700's....) My LBS likes to build up Deep V's for his single speed customers (lots of messengers) since they stand up to a lot of pothole/curb type abuse.
