Brian:
Is there a way you could post up some video of Michael Finney's swing? I do a search and only see the one of him hitting a driver. I feel i can watch and pick up things by seeing the visuals. Thanks.
LCT helps those who have lag problems, not open clubface problems.
Twistaway is meant for those who have open clubface problems. Once they have SOME control over that you could induce some LCT in their takeaway to get the club in a "less twisted" position if that makes sense.
You could combine the two kinda, but it's too much "work" imo. You twist them until they hook it and then you untwist them to the point to where they hit it straight.
