Sorry to hijack the thread but my pro has been getting me to use this regularly to try and coach out my fat shots BUT he also gave me a quick driver lesson and advised me to take the wrist hinge out(due to me having an awful slice) It helped greatly though recently I've not been hitting it well) Does anyone know why this helped? I'm guessing I lose a lot of power without wrist hinge? Was going about 210-230 which I was happy enough with.
