I understand the reply of both Yoda and Matt, however, I am in a similar predicament as birdie_man......I need to feel as if my left arm swings the club, ....the rhythem of the left arm and club together.
Whenever I do or feel RFT, I lose the feel of swinging my left arm, and it feels more like a punch swing from the right side (since during RFT, my right arm produces the feel of the swing going back). With STT, I feel my left side (shoulder and arm) swings back and my left arm swings through.
Additionally, I have yet to get good results by letting the pivot "swing my left arm and club"....I get much better results when my left arm "swings the club"
