Hue,
I use a plane board periodically. I dont like to use a club with it, it just doesnt have the same feel coming down the board. Instead, I use a cut down stiff bristle broom and it works perfectly for me. I take it back and through. Over and over. Then I hit balls, then go back and do it some more.
The other thing I do sometimes I step into the planeboard a few inches with a club so the club is actually a few inches outside the plane and take 3/4 swings, full swings but I choke up so I dont hit the ground. Oh yeah, my board is full size and made of pvc, not wood. Wood is too heavy to move around, etc.
