Basically my normal rotation makes Rory look stiff - I have a massive overswing, on my upswing my club goes past perpendicular with the ground and finishes about 40 degrees past that. Have mostly corrected it now in my irons so that I no longer over-swing - I've gained a lot more accuracy as a result, but the downside is I've lost around 10 miles of club head speed, so my irons are around 5 to 15 yards shorter than previously.
The question I guess, is how do I get that club head speed back, now that I am no longer able to use body rotation as much?
