Welcome to the board! It's always good to see v-drives show up here, especially ones with such enlightened color schemes as yours :-) A pair of new S22s...it's turngin out to be a good week already!
I remember how it felt when Pete's site showed up on Google. So cool to have, and I hope we eventually host the whole Epic community.
I agree that our v-drives are sensitive to fore/aft weight distribution, but do believe they come out of balance from the factory. I think that each S22/SX needs 200 pounds in the very nose (permanently) to fix the stock out-of-trim condition. After that's done, they might be a little more normal in terms of sensitivity to bow rise, porpoising, etc.
As far as side-to-side sensitivity goes, you should go ride on a peaky-wake boat like the SAN. Keeping those wakes clean on both sides is like a balancing act compared to ours.
Can't get a pic up cuz I'm on NT here, friggin Paint won't launch (couldn't make jpegs anyway), PhotoEd won't run cuz of NT, Quiktime viewer won't allow me to edit....
Oh yeah, ballast: 700 pound Big Bump in trunk and second Big Bump in walkway as far forward as possible. They're friggin huge, and were super cheap around Christmas time last year (gethighsports.net). Only one other bag will fill the trunk better, and that's the $200 Fluid Concepts 1000-pounder. I don't use the covers, and fill both fully. Site says 700 to 750, so maybe we've got 1500 in there, not sure. Then again, I'm not happy with the hole shot with this much weight when we've got a bigger crew. Takes a good stick, too when you've got her loaded up (enter Perfect Pass).
