I had a great lesson with an NG CI. He spotted my flaws regarding motion and inappropriate effort, and adjusted my grip slightly. He gave me a swing key I've not heard before except for one Moe clinic on youtube. It works wonderfully for improving my timing and lag. My swing felt effortless yet the balls just took off. I don't want to go into it at the moment because I'm not up for the inevitable naysayers. I want to keep positive thoughts going.
