What can I do to work on increasing the snap of my backhand drives? I knew my sidearm throw was longer than my backhand, but I didn't realize how much further 'til I measured. For golf D, I'm around 325 with a lucky 350 here and there. But I found out that I can consistently hit around 420-440 with a sidearm.
First time I did it was on the course, but I figured they hadn't measured the distance properly so I went to the field and measured out 450'. Time after time I was hitting the range I mentioned and my accuracy always kept me within 40' of my target.
I want to be as proficient with backhand, so what can be done to increase my snap on backhand drives?
