i have 2 fists and a 130mm stem on my mark v - there's about 3" difference from seat to bars. i've gotten to the point where the seat is pretty far forward, but there's no weight on my hands when i'm in the drops. i'm not the most flexible guy, but i ride every day - 40+ miles a week. I feel faster shifted towards the front of the bike, and it just seems to suit the way i ride. That said I had to condition myself into it.
