You may have to pay Martin Hall some pennies.

I saw him doing the drill on TGC at about 3 in the morning. Usually I don't like (or do) drills but I gave it a try and found the downswing plane for the first time (for me anyway).

Since discovering it, I have used it with students at First Tee and it works great for them too. The only problem is that their flexibility allows them to come under plane a bit.

Have fun.
