I am not sure you endorse the elbow plane product (whatever that means) or it helped you to the point you don't really need it. I know the wrist product was very beneficial. The elbow motion is A bit more subtle in determining the bend in the bend in the backswing and the straightening of the right arm in the downswing location wise.If there is any additional infomation than you can supply going back to when you used it I would appreciate it. Sometimes I know that is hard to tell as your own swings or hits evolve.
I do endorse it (tac tic elbow) as a product that does help with 1 particular area (extensor action). I will probably go back to using it, but I haven't used many training aids lately during the season...I try to know play as much as possible and when I am at the driving range I still work on different things, but usually not with training aids, unless I know a particular one could really help.
