Had a mini lesson yesterday as I wasn't hitting my driver much further than my 3 wood and wanted to know why
A simple set up change putting me more behind the ball, more tilt of my shoulders and that almost instantly got me hitting it 15-20 yards further and mainly carry too, added around 10 mph to my ball speed too and still pretty straight, was buzzing
My best drive went 275 with 110mph clubhead speed and 140mph ball speed, my best 3 wood was just over 250 (this is on a simulator with zero wind factor, etc)
I said to my coach what do I need to get to to be able to hit it 300 if at all, he said minimum 130 clubhead and 160 minimum ball speed, he reckons with some more technique tweaks (driving down into the ball more a la Rory when he drives it) and improving my core strength too it might be achievable (I start at the gym on Tuesday)
He for me is the best driver in golf
