It can be real interesting when talking about vertical gear effect though and in that regard, CB irons will reduce the amount of spin which in turn reduces the curve. In a small way, I do think CB irons, with all things being equal, will curve less slightly. JG John,

If hit on sweet spot, is there any truth to this? It seems that a ball would react similarly on both. While pros tell me you can't spin a modern ball with a CB iron, I can bring them to any range and show them 20 handicaps moving the ball 20-30 yds left to right without much athleticism (albeit uninitentionally).

Many thanks for making all your material available on the internet. My understanding of the ball flight laws has improved immensely since I first found your website a few days ago. I don't think anyone explains it as well as yourself. The information on the straight shot was a revelation to me, and I can see that a good understanding of the D Plane will help people to become more precise in shaping their shots. I have read your blog article on how to curve the ball the right amount. Do the numbers from Trackman in your article apply to both the push draw and the push fade? I expected to see a different numbers for each taking into account the effect the 'angle of attack' of respective clubs into the ball has on the clubface angle at impact, and as you have said so yourself it is easier to fade the ball than to draw it? Secondly, can you give advice on how far to the right or left of the ball to target line should the golfer aim the clubface with each of the respective clubs to produce a push draw or fade? What would be the minimum and maximum offset angles you could use? Lastly, what is the main factor in causing the ball to hook or slice? Keep up your excellent work. Paul John,
