I'm playing 1998 Top-Flite Tour irons. They were low end irons even when they were new but I hit a lot of clubs before I chose them. I've been mostly happy with them and haven't really been compelled to change. I was even reluctant to give hybrids a try because I like my long irons. However, I recently added Bobby Jones hybrids to my bag and can't believe the effect they are having on my game. I'm wondering with the new technology and custom fitting of irons if new irons could have a similar impact on my game.
The last thought I have before I begin my take away is "don't hit the ball". If I think about hitting the ball, my swing is jacked. I want to simply swing the club and let the ball get in the way.
Many times the difference between the low-mid 80's and the 70's is getting up and down. I spend at least a couple hours per week hitting balls from 30 yards and in. I'll pick a spot and hit 10 balls and won't move to the next spot until I get 7 out of 10 up and down.
Davis Love III is my all-time favorite player and I absolutely love his swing. I even like the "tempo" with which he walks the course.
Lately, I've found myself watching the LPGA much more frequently than the PGA. There are a few swings on the ladies tour that I really, really like.
Get a Bobby Jones Hybrid by Jesse Ortiz. They are absolutely the best clubs I've ever hit. If you are hitting your 5w about 190, then I'd recommend the 17 degree as a 200 yard club. My 5w was about a 215 club for me and I replaced it with the 17 degree Bobby Jones and it's a 230 club for me on the best hits and even the bad hits turn out well and still go over 200.
