I haven't really got it beat im afraid Pnearn. All I know is that as long as I swing along a flatter plane and attack the ball from the inside, the shot shape is much improved instead of the big looping draw ! get a nice 5-10 yard draw. The reason its more pronounced in the higher
clubs is because they are harder to start off online in the first place due to the greater loft. Its just exaggerating the overall effect. One tip of course is to always take one club more and you will be more accurate (not by much but every little helps).
