You don't want positive pitch below 3/8 -7/16 stick with the throttle trim all the way up. The added pitch will slow the head and you'll get the wobble. The 9T does great. I fly mine to just a hair of postive pitch at half stick and throttle trim all the way up. This alows it to hover at mid stick for me. Someone metioned awhile back that your blade grips might be to tight causing the wobble.
