Forget the idiocy of this question and the obvious answers. You or your Swing coach?
I went back to my swing coach for a short game (pitching inward) plan to get better. Before he looked at my short game he looked at my full swing. I have always had an over swing and leg movement in my swing in the last year that has been reduced in my irons and a out-in swing changed to in-in. Because he sees a short game plan as wanting to get between he wanted to adjust my setup again to reduce the leg movement even more (hips set closed and pushed forward ar la peter lonard (arm swing not body)) better the approach shots the easier time your short game has
I’m ok with the swing change (hard to do) but will to do it to try and improve. I said I was have issues with driver shots eg if I use a LD swing & club I hit the fairway a long way down and 70% of the time. With a golf driver and swing I’m shorter and I hit less fairways 50%. Stats back this up in the last 5 rounds. He wants me to drop the LD swing as it can effect my iron swing (I agree but I’m much happier with my tee game when using a LD swing- I trust it). He cann’t see how my LD swing could be more accurate (relies more on timing). As my upper body is not that strong I prefer a body swing for power. Since I went back to a body swing for LD I have picked up 20mph, accuracy and distance. I feel I have a lot more room to grow quickly with a body swing. Or do I go back to basics for possible long term gain?
