Personally, I try to get the feel of what my right hand is doing...what alignments it has...where it's going...etc.
I really try to watch that wrist throughtout the swing. It's my only focus, really. I bend it backwards (I have a very neutral, weakish grip BTW) and pull it back, up, and in. Gotta get that "clapping your hands" feeling with the right arm.
And yes, right forearm pickup is favoured by TGM. I used to think it was kind of awkward but if you do it right it feels great. Gotta pull back so you feel the pull in the back of your right shoulder.
