I think the best way is the wing tip (dropping ) method,when upright,move rudder oposite to the dropped wing,inverted,move the same way as the dropped wing. Its the same as when you first learn to fly,you have to do it until you dont have to think about it anymore,you dont have time to think about it DOD & TR fast. What made an instant and dramatical improvement for me was the article in Hangar-9 web site by Don Szczur. He states that you handle a TR like a slow roll,since I had been doing that along with 4 pointers,8-pointers, it clicked. After reading that & putting into practice,suddenly my TR's really kicked in, I mean they spin so fast at times I can barely keep up with them. I think this method really keeps the plane in that "sweet spot" longer.
