Don't go overboard whith making the wing thick. Thick wing profiles give more lift when they are not stalled, so you can fly around very slowly..... but they can fly very slowly, so they won't stall. Meaning the plane wont harrier well, it wont blender very well and it wont snap well at all.

3D is more than just hovering, and freestyle is more than just 3D. I would build a smaller version of your pattern ship, with a slightly thinner root and with a huge elevator and plenty of power. The best freestyle ship that I have is my 140 pattern ship setup with twice the elevator movemant than I would normally fly with. And the worst is my profile fun fly unless the wind is absolutly dead calm.
