Jetfan, the protracer stuff is great eyecandy but I'm not really sure about what it's significance really is. I know my views on this stuff are unpopular on this site but at the risk of another ban here goes. Just about all of those shots are performed by pro golfers at the peak of their powers and the wisdom here is "do as the pros do". I think that's flawed logic, but that's a discussion for some other time.
Yes the ball will move in the air, nothing is dead straight, but that argument seems to miss the point.
When I hit the driver I'm looking for neutral flight......sometimes it's pretty straight, sometimes a fade, a little bit high, a bit of a draw, etc etc. I'm not that good a golfer that I know exactly what's going to happen. And I reckon most 10 to 20 handicappers are in the same boat.
All I want is not too much of anything. All I'm looking for is to keep it on the fairway and keep it neutral. My big decisions about my driver are where the wind is blowing from and what is the slope of the fairway.
Today I hit 12 fairways and missed 2. but the shots included 1 nice draw, 1 blocked left, 1 super high pull, 1 drag to the right, 1 fade..........but they were all in play because I made a judgement about wind and kicks off banks and slopes etc. My point is, neutrality of ball flight is my aim.
Also, you'll notice on the protracer that nearly all of the shots hit fall straight down after drawing of fading. Lucius Wooding pointed out on another thread that the swing speed of pros allows them to hit the ball on a lower trajectory with enough spin and still have the ball drop at a steep angle to the ground. This is what you see on the protracer. So what happens when you shape the ball with a slower club head speed. Would the ball still be drawing or fading when it hit the ground?
Also, to hit these controlled shapes the player needs to aim properly. It sounds stupid, but how many times have you stood behind someone and they've driven the ball exactly where they were aiming it.......straight into the trees on the left. They thought they were lined up just right, but they weren't. Now add a shape on top of that.
Wouldn't a better approach be to aim in an area, a general area of 10 or so meters wide and try to hit a neutral shot into it.
Also(still awake?) "overcooking". I see my swing in 2 major elements, the clubs path and my hands. If I hit in to out with a slightly closed face, I'll hit a draw, if my path is straight with a closed face....Im in the scrub......To me, I find it very difficult to make fine judgements about either of the two elements. And remembering that the combination of the 2 is where the danger lies. So I'm going for neutral path and neutral hands. Sure there's a bit of hit and hope in there but it's an educated guess if you know what I mean.
That's all I can think of ....so far
