…grip pressure issues and touch around the green.
This may sound strange, but I have had great success with a few students doing this.
Take a club that is a backup and cut the grip off. A wedge or short iron of some sort. Get strips of bubble wrap and epoxy it and fashion a grip.
When you hit balls, it will give you great feedback on your grip pressure.
This works exceptionally well on chipping and pitching around the green.
This is as complicated a training device as you should use.
