If you're going to change after 20 years, you might as well know that you're going to have to move A LOT more. You guys are full of BS when it comes to the DTL backhands. I know quite a few people that prefer to hit DTL with their 2HBH. Go get a ball machine, a few lessons, or a buddy that will hit balls to you. You'll be fine as long as you PRACTICE! BTW it's more like a left handed golf swing than anything. Your right hand is still doing most of the work, your left is there for guidance/suppport. Shoulder and trunk rotation is a big part of it too. Have fun.
Junkball IS an option. Losing is not.
