thanks for the reply Jerry, i was hoping 'aft of the shaft' for the left thumb was as you describe. It is a great start for me as it is the only place my thumb wants to go & i'm delighted to hear for the first time that it is ok !
''I can be a bit doltish. Go to The Book and find Strong Single Action grip. I think that is the best place to start.''
I'm new to the whole deal, would you tell me where i can access 'The Book' - thanks
