Chris, I'm trying to fly whenever the weather allows, and am not travelling over the holidays. Let me know your schedule as the time gets closer. When I tried the Integral a lot more nose heavy, I didn't like the 45 and 60 degree lines, or the excessive elevator for inverted. Snaps were a bit better, but I've finally got the throws about right for decent snaps. It's even continuing the loop on the 1 1/2 snap avalanche instead of flattening out!

I agree that there are factors other than the simple plan form of a wing that determine center of lift. For example, it would be kind of tricky to factor in an eliptical wing tip, and I too have heard that center of lift can move with air speed. However, my experience has been that this formula is a great starting point for those who don't have plans or just want a second opinion. Pattern has always been about the latest in fads. There are a lot of people preferring the CG more forward now, and I generally believe in going along with what the majority are doing. But for CG, I really do prefer closer to neutral.
