With a one plane swing you can let the club rip and release right from the top of the downswing as hard as you like, do not create any wrist lag like you would find in a two plane swing.
The one plane golf swing is identical to a baseball swing but instead of hitting the ball at waist level you are hitting the ball on the ground so just bend over a little more.
Determine the ratio of the distance the ball must travel in the air to the ball rolling on the ground and select your club accordingly
