I'm exactly 210lbs and 5'11". I whizzed thru AFF much quicker than the floaty guys I know - I put it down to more weight - more inertia - more control (my bit of self delusion - but hey it works). I was concerned when I started to skydive that I would be too heavy to fly with other who were weighing in at 170llbs. I couldn't have been more wrong. I don't have much experience flat-flying, so I still struggle on the bigger ways, but if I'm just 1 on 1, I'll just hold on to the skinny wretch until I can level myself off (only joking Ivan)! However, for freeflying I feel I have a distinct advantage, esp. in transitions or cartwheels, where you lose your more streamlined position. I find keeping up the speed relatively easy where some of my lesser experienced friends just cork and lose the pack. I also feel I have much more control in speed. From a slow sit, I can fall around 140mph and in a head-down do way over 200. All in all, as long as you aren't particularly heavy, or particualrly light, you wont find difficulty in having fun and keeping up with the rest. Later, Rob btw - buy a dark coloured jumpsuit - I bought a yellow one first and shadows are not a good thing :-)
