Tee - The green line in this lead wrist graph is what counts in this post and deals with lead wrist flexion/extension in degrees. The black horizontal line = neutral (no flexion/extension). Below the horizontal black line = lead wrist extension (cupped). Above the horitzontal black line = lead wrist flexed (bowed). BTW - I didn't digitize this player and there could always be a problem with poor digitization. Post some of your lead wrist graphs there Tee! I know you have them and you could bring some precision to this issue on what truly is a "flipper." What is a roller is a whole differnt topic. We don't got direct numbers of that as I found it too complicated to measure in 3D. I have to read it from paths, hand /CH relation and some other positions and would be too difficult to explain how to see what. What makes me wonder is that there doesn't seem to be any reaction for impact as there certainly should be. I guess that is the old filtering problem as I've told before. Impact gives totally different impulse to the wrist for flippers and non flippers and amount of flexion should change sharply at impact.

I thought you wanted tour players? I'm not a tour player!!! You've seen my swing before on YouTube when it used to be up. In fact, you tried to give me somes swing tips after you viewed my swing. Plus, I'm a flip/roller! I don't want to lose 118 mph swingspeed and don't care if it goes in the rough. Just who I am as a golfer and I accept my kinetic limitations and benefits. For me, the game is about length.

Jeffy - Is the graph I posted that of a "flipper" according to your definition of a flipper? Seems awfully close to a "flipper" if the term flipper is tied to the lead wrist (which is where you draw the lines for a "flipper"). Could be an underflipper, could be a flat DHer, might be a roller. Can't tell much without the trail wrist graph. Just post some good high-speed video and I can give you my opinion. Also, what is the frame capture rate? And are you sure impact is indicated in the right spot?

Plus, I'm a flip/roller! The video wasn't very good, as I recall, don't even think it was face-on. Sorry to hear you're a flip/roller. With your physical gifts you might have been a player with a decent release.

Anyone, don't know why anyone would use that system for research given that six-camera systems you can use outdoors are available for around $100k, or so I've been told.

For me, the game is about length. Why would you lose swingspeed? Lucas went from 108 as a flipper to 120mph+ with a drive/hold. Hits it high and straight and can move it both ways. Kelvin has been working with a guy on the mini-tours with a 120mph swing speed, switched him from a flip/roller to a drive/holder and he's picking up distance.

Plus, my herniated disc and left hip aren't the best. I'm 42 which doesn't help.

Imagine the bad conclusions that are drawn from one video camera! I hear yeah Jeffy. Yes, that's why it is important to use multiple camera angles. But it is pretty easy to accurately tell if the shaft is passing the lead forearm from a face-on video at 300fps. Not everything has to be rocket-science!!!

I'm very happy with my improvement and my scores have gone down considerably over the past two years. People over 40 who think they can have a tour level game are nuts IMO. The Tour is a full time job!
