I can tell you that my question was based on a recent comment I read where someone had said their swing had been ruined by 'swinging out' which I considered a bit strange as the only way I can figure a push-draw with a driver is with a large HSP angle..... just found out earlier that McIlroy 'swings out' with a HSP of 10-13°... so that's the 'swinging out is bad for you' theory down the toilet! :) Obviously with an iron it's not necessary as the ball is hit on the back side of the circle. Thank you for your time and consideration of your reply... maybe you should do a push-draw DRIVER video for Youtube? I couldn't find one anywhere (fingers crossed you don't already have one and I missed it!!) Ha! regards... and a Happy 2012 James. John, thanks so much.

I’d appreciate it if you could define geometrically the proper way to hit PUSH-DRAW with a driver. Can you please crunch the numbers for D-plane (trackman stats) for a PUSH-DRAW with a driver hit at +5° assuming the feet are SQUARE to the target line.. I figure you’d need to be “swinging out” with the base of the plane pointed considerably right of target? Thanks in adv….." Golf Happy, If we assume a vertical swing plane of 45º and a push draw that lands at the target assuming a centered hit, there are many combinations that would accomplish this with the only stated variable of +5 AoA. Here is one such combination: HSP +8 creating a club path of +3 because of the +5 AoA and 45º VSP. Match that with a club face of +2 (for right handers) and you will get a push draw that lands at the target.

Happy to help. Yes, it does matter in terms of how much of an adjustment would need to be made for the golfer. If they wanted to hit a curved shot (pull fade or push draw) assuming the same plane angle, a golfer with a steep down angle of attack will have to swing/aim more left than the player with less angle of attack. The opposite is true for hitting a push draw. JG John,

I am now really get a good overall picture of the D Plane. One more question if I may. It is in reference to my last question and answer concerning the AoA and plane angle. In regards to my last question that you answered for me does this make any difference when trying to play a pull fade and a push draw in regards to the angle of attack and how much one has to allow? hope that this question makes sense.

The angle of attack in the other example was 1 down so the club is still moving out until it reaches it's lowest point. If the Angle of Attack is zero, the swing plane angle won't matter. Once the angle of attack is positive or negative and adjustment will need to be made to account for that. Hope that helps. JG John,
