Yea so this whole post is because the ping rep at the tent said my distance dropped probably because I had that attack angle on the positive side so causing too much spin and loss of distance. I was testing a G400Max. I currently game a G30LSTec for the last 3 years and my average carry (course data from Game Golf says my average drives are 275, which I'm happy with. I currently have the head set to 9.5. It's been a while since I've been on a monitor with it but if memory serves me I was getting launch angles of 13 ish and spins at 1900-2000.
I've just always wondered if 9.5 was too low and if I'm losing any yards that way.
Plus my ball striking has been a lot better over the last year and a half.
Angle of attack makes no difference what so ever to spin, its a old myth killed 10 years ago by Trackman, and this is the very first time i hear that a POSITIVE AoA would gain spin, but there is no connection that way either. On drivers, spin is mostly vertical gear effects due to impact location on the face, so if your spin value is to high, your impact on the face is to low, its that simple.
Howard. First off I know very well that you know what your talking about. But. Take me. Very high spin player. Trackman verified 115 plus or minus average speed. And a very consistent in to out path by a degree and repeatable -3 AoA. Average spin with any Driver I tried ( 20 plus heads and shafts as I have access to a lot of good stuff ) would average at the lowerst around 2800 rpm. And at the highest 3800rpm. My strikes are 99% higher than center on the face with a miss that strikes very high in the face ( near Skyball). I can't hit it any higher on the face is what I'm getting at. And I too was told " level out your AoA ". So I've worked hard to do that. And on swings when I get it leveled out I see 20-30 yard jumps in carry and spin Down to 2k ish. Thoughts ?
Problem is it isn't a natural swing to me. And I struggle to repeat it on course.
It sound like you are not closing, but de-lofting the club trough impact, and by that make the same gear effect that a low impact causes.
A negative AoA of -3 with the driver is a lot, so whats your AoA with irons?
Honestly do not know. I hit them so well I don't care. Lol. Seriously though. Driver has always been my struggle. I'll hit a 15 degree 3 wood longer than Driver most days. And yes. Closing the face is also my miss with Driver. As in miss will be a push fade. Or high right.
I'm an upright swinger. Tall playing Driver at 44.5. 5 iron is 38.75 inches. Don't take a deep divot. When I'm really on it's a 6-8 inch long divot. Shallow but even. Definitely not a digger. Always hit thin sole irons best. I'll take a shallow divot After the ball with a 3 wood too most swings.
Sounds like closing the face is more important than AoA. ? My bandaid for that is starting it shut at address. Brings in an occasional hook. But eliminates wide right. My trouble is that my release is very much tied to my body turn rather than hands with irons. I'm so upright I just adjust Path slightly and if I have face square to that at impact I hit a draw of a fade. Trouble with Driver is it requires some more hand action to get the big head squared up. I can do that. It's just a new action. Which feels like a flip to get the face closed. It's amazing him much spin I can put on a ball.
Face angle is direction, so yes its the most important, while Angle of attack makes a difference for how much launch we can get from a certain loft. With a negative AoA we need more loft to get to the same launch angle as a player with positive AoA, and thats the indirect connection to spin.
If we say we had 2 players 1 with a AoA of minus 3 and the other with plus 3, and they was playing the same static loft, their spin values should be equal with the same impact spot, but launch angle would be very different. If the player with negative Aoa wants the same launch as the player with a positive AoA he will have to compensate with more loft, and using more loft adds spin.
Make sure your impact is close to the club heads vertical center of gravity, that means we should start by measuring out where that is, and anyone can do that, its quite simple. You can follow this link into my DIY driver tune up and you will find a explanation with photo illustration on how you do that.
About your swing and errors, they are like i would expect, so im thinking "how constant" is your BALL SPEED ?
if it vary a lot, or your average smash factor is below 1.48, my suggestion is that you slow down and hold your focus on your swing and impact. At the moment (with only a few parameters as info), you seems to be more focused on gaining club speed than how the club is delivered to the ball. Your club speed is the he higher end, and that means you loose even more of your potential with a "not so good impact", compared to a lower club speed player, so only a tad slower might improve it all big time.
Here is how it might look for different club speeds.
90 mph with a smash of 1.45 = 130.5
90 mph with a smash of 1.50 = 135.0
Difference is 4.5 mph ball speed x 2 = 9 yards
100 mph with a smash of 1.45 =
100 mph with a smash of 1.50 =
Difference is 5 mph ball speed x 2 = 10 yards
110 mph with a smash of 1.45 = 159.5
110 mph with a smash of 1.50 = 165
Difference is 5.5 mph ball speed x 2 = 11 yards
115 mph with a smash of 1.45 = 166.75
115 mph with a smash of 1.50 = 172.5
Difference is 5.75 mph ball speed x 2 = 11.5 yards
As you can see the high club speed player looses more yards than the others if his PTR value /smash is to low (no good impact), so lets just jump to BALL SPEED. A Good impact from a club speed of 110 with 1.5 PTR gives 165 mph, compared to a "not so good impact" from 115 with a PTR of 1.45 gives 166.75. On the paper that gives 1.75 Mph difference only or about 3.5 yards BUT the impact with a PTR of 1.5 would have LOWER spin value, and more "correct" launch angle from that loft, so this shot will be the longest and the best
Find out where VCOG is on your club head, and slow down a few Mph on your club speed and have focus on your swing and impact, NOT your club speed, it will follow back up again when the rest works better than now.
