I hit my driver significantly shorter in comparison to my irons. I hit my 7 iron about 165-170 and I'm lucky if my drives get out to 240. I hit the ball very very high, I would like to hit it a little lower. My college roommate who is a pro in Texas says I have no lag. I have been trying to work on it but it seems like a bigger problem that just a couple drills could fix. Any ideas?
