Thanks, Comet. Regarding the Vertical Hinge Action on a "full blown 6-iron", I hit exactly that shot for Alex and Burner in their private session the day before the LBG Homecoming Classic at Cuscowilla. I swung down and through, took turf, and the ball went dead straight; but . . .
Sky high!
Tell'em about it, Alex and Burner!
I showed them the same on the 11th hole with a 7i. BJ was with us and was having a chuckle that it was the only ball sitting on the green)
