Jon_UK the thing that blew my mind when I first went on a Trackman was that you basically never want your club face aimed at the target at impact. Isn’t that strange and paradoxical?!
With a square clubface, the only way you will hit the ball at your target is if you have a totally neutral (0.0) path, which is essentially impossible to replicate. If your face is square to the target and you have a right path, your ball will actually curve to the left of the target and you will miss left (and vice versa for left paths). What this means in practice for you as a drawer of the golf ball is that you need to have an OPEN face at impact. Just to make up some numbers, if you have a 3 degree right path with a five iron, you probably want your face about 1.5 degrees open at impact. If you face is square (or god forbid closed) you will hit a hook that crosses your target and misses left.
Another interesting thing is that your path changes depending on ball position and the length of the club. You will have a more pronounced “draw” (right) path for short irons than you will for your driver, This is because the ball is further back in your stance for short irons so you the arc around the body will send the club more naturally to the right. With a driver, the ball is off your front heel, and so the natural arc of your swing will encourage the club to be headed to the left at impact. In fact, Jon Rahm has a right path with his 9 iron and a left path with his driver!
I encourage you to go have a session with a launch monitor. All this will become totally intuitive once you see how it applies to your own swing. As you can see it’s about way more than just nailing down yardages (though this is helpful). I could write another entire article about how Trackman has changed my understanding of how to play wedge shots inside 50 yards!
