RE: To pinch or to Thumb....
I started using thumbs. But I held the transmitter at first. I could not control the sticks well. A friend gave me a spare neck strap. When I used it I found I could pinch the sticks and have better control. Now I am a pincher and use a wide neck strap. The thumbs was mostly because we had no buddy boxes back then. I say whatever is the most comfortable to you is what you should do. And the heck with whatever anyone else has to say.
