Had a lesson today - I was convinced before I got there that I was swinging OTT
Instructor said no way - if anything its inside out.
He said my grip was causing lack of release - I asked if I should try and roll hands over earlier - he said that's a no-no and that release is the effect of good grip pressure, swing path and grip being neutral.
It felt horrible going to neutral grip, if anything I felt like I had metal rods in my arms.
I couldn't argue with the results...
