Dear sir,
The RH LH switch over takes about 2-3 minutes ( for me ) on the Hands Back Hitter. The arch on the HBH keeps a batter from lunging just like the hip resistor on the Stayback Tee just at a lower level. You can buy 2 HBH for the $ of one Griffey tee.
Just updated the site with animated gifs and putting in a free download for the promo that should be done by tomorrow..take a look.
e-mail me and give phone # and I will help you out donnybstr@aol.com.
I am going to let my 17 yo try to beat me in golf right now. I turned 50 last week but he still can't win....I hope!
