JACK- THANKS FOR THE INFORMATION. I'M ALWAYS TRING TO WORK ON TONE AND SPEED. I JUST HOPE I DONT PASS OUT AT WORK(OR WORSE YET, IN THE CAR--EVERYONE'S FAVORITE PLACE TO PRACTICE) WHILE DOING MY WORKOUT. ANY OTHER RELATED MATERIAL YOU HAVE WOULD ALSO BE GREATLY APPRECIATED. JUST TRYING TO BLOW THE BACK OFF THE DAMNED THING. DAN.
