I've been Playing Golf for: 4 years My current handicap index or average score is: 13 My typical ball flight is: low draw/straight The shot I hate or the "miss" I'm trying to reduce/eliminate is: Long iron miss hits Videos: driver face on- driver down the line- 7 iron face on- 7 iron down the line- Couple things I notice I do wrong but am not sure how to fix: - My left knee colapsses in and I sway - Almost no hip turn in my backswing Any feedback or drills to help will be much appreciated. I live in Canada so I only have about 2 months left of golf. But I am going to be getting lessons next spring. My main problem is I can't hit a 7iron and down at all. I shoot low 80's and high 70's once and a while so I am not terrible but my short game really saves me because my ball striking isn't great. Thanks for all the help guys.

2 weeks ago I was consistently shooting high 70's to low 80's. Now I'm lucky if I break 95. All my tee shots go straight up or slice compared to my little draw I was hitting. I also only hit 1 of every 3 iron shots solid. How can I get so bad in a matter of 2 weeks when I haven't changed anything?

My club speed is 90-93 mph. I have never stuck to one kind of ball before, I would just use what I found at the golf course I work at. What is a good ball that has excellent spin control that would be best for my swing speed? I have used tour balls like prov1 and have excellent spin control with them but if I hit a bad drive they have an excessive slice or hook. What about the bridgestone e5?
