I have had the new swing stick for a few weeks now and have found it to a great device for developing both speed and proper lag. To me the most important thing in your swing is proper lag. I have a golf buddy that just could not figure out why he was not hitting the ball solid consistently. So I had him do a few swings with the speed stik and found that the crack was occurring well after he was past the ball. I told him to hold his wrist cock slightly longer to produce more lag and sure enough after some practice the crack was heard where the ball would be. Going to have him use it this winter and we will see in a few months what it does for his game. Will let you know once we are playing again.
