So I started to pick up golf a week or so ago and have been going to the range. I've been hitting my irons well but I can't hit my Driver. I hit my 6-iron 185+ and my 4 hybrid 220-240 and they go very straight. Not always where I am aiming them, but they go straight.
However, my Driver goes only ~165-200 and slices so far right. Any suggestions on how to stop slicing it? I hear that I should keep a closed club but I feel like I already have a very strong grip. Is there anything else that leads to slicing? Is my club too long?
