Wow, I wasn't going to mention this but now I have to. I have a good friend who tracks very high and inverted like you. We played with a R.Fuel and placed the pin in the track 9:00,cg in palm and mb at 3:00, everything in line straight across horizontally, guess what? Yep, he tracked full roller....I thought I was losing my mind...strangest thing I've ever seen. Okay, if your getting the same reaction as my friend, a stack lev will also tend to lower your track some, it should pull you off the fingers and thumb so you're not as high. This is what he gets when we do that....thanks.
