Handle rotation as in the grip tumbling over itself like a baton, or twisting?
Hand strength?
Thanks Brian for posting these numbers and findings. When you were doing your spiderman finish where in your swing did you consciously try to start trying to move the bottom of the grip past the top
Brian,
Much obliged to you for posting this video and your recent torque video. Great stuff and very interesting. Is it your feeling that these findings are calling for moving the handle -- if pure speed is the goal – more like a lacrosse shot or hockey slap shot? (See attached links of slow motion record speed shots in lacrosse and hockey). It looks like they are actively pulling back with the top hand as the bottom hand fires through. If so, is the difference between that and a flip simply where in the swing the hand action occurs?

Hand strength is large
Yup.
The exact thought.
Interestingly, we ask Dr. Nesbit if a baseball player had "force across the bat" at impact, and the quick answer was no.
It's something that people talk about because they think it's a big damn deal.I always thought the rate of closure discussion was related to accuracy rather than speed?
You related face rotation to clubhead speed, it varied between the different swings you made.
The numbers seem fairly small, 300 rpm I think you showed, can that be equated to how open or closed the face was, does say 500 rpm mean a 1 degree change in face angle.

Sure....Brian, could you post the numbers here on the thread again?
Btw. did you try to do your best 'handle dragging' swing as well for comparison?
Very interesting indeed!
Greg,
Now you know what handle dragging is, and why we don't really teach it anymore.
Working on rate of closure won't get you ANYTHING you think it will, unless there is a placebo effect. And it MAY slow the club down.
Sure....
Just looks like he lines it up later than average, and with great athleticism. You can see from the video that his body slows down and he slings his right arm straight, he's not just rotating IMO.
IMO its just a matter of preference. Line it up early or late, whatever you want. The only thing that matters about having that alignment IMO is whether or not you have a bunch of force across the shaft, which I find the less the better, and a freewheeling clubhead. You can see that DJ is freewheeling the clubhead thru impact, while some "handle-draggers" are trying to rotate the whole body and clubshaft together at the same rpm's a la TGM "rhythm". Not the same thing IMO.
IMO, just means you MIGHT not be getting as much speed as you could if you "rotated" the grip faster, as defined/measured by the ENSO.
