Actually Daltons 'method' (to call it his method is a bit of a joke as it's as old as Tom Morris) is used by lots of Long Drive Competitors where the release comes way before the current DELAY method Pro's are TOLD to teach today by the PGA. it goes back to old school, Bobby Jones, even Nicklaus where the first thing that moved on the downswing was hips and wrists. It's not new & it takes a lot of time & a LOT of practice but it does work. Old wheezing Dalton looks likes he's about to have a heart attack half the time though. Also the vid was up against trading standards and got pulled eventually cos they said no one can 'guarantee' straight golf shots!!
make your own comparison, but a similar but not identical method that REALLY DOES work with no gimmicks is Mike Austin method. 20 YEARS AGO At a ripe old of 64 Mike drove a soft a shit ball with a promisson head driver 515yards in an official PGA tourny. OK 23 mph tail wind but it was not down hill and it is STILL the record with David Love III second! The ball carried 460! This bloke regularly pinged it 400 with ease at 64! Say forget your new fandangled FT-3's and G5's with Pro V1 super hype kit and balls! Learn to hit the ball with full leverage & efficiency the way body was designed and not by some PGA Pro who is TOLD what to tell you.
WORD OF WARNING: Mikes method will screw your head up. You will perform complete opposite actions to current PGA teaching methods. Mike was always at logger heads right up til his death last month with the PGA instruction method. He summed it up perfectly about good players through the PGA prog 'You can perfect the inperfect' RIP MIke.
Sorry this so long but I beleive in Mikes method, although Dalton tries to pass this accross he doesn't manage it at all. His tyre drill is a must though!
