Winter Practice

Tom,

I'm in NJ. I'd like to continue working on your drills and my swing during the off season. Do you think hitting off a mat into a net has value? From your videos I'm guessing so, but wanted your thoughts about that. Maybe special things to work on since no ball flight feedback? At the range, when open, frozen balls go about 150 yards max and float like a knuckleball!

Thanks,

David
