johnnydoom Dynamic Gold S300. I play them consistently (on the rare times I play anymore), but cannot hit a draw with them no matter what.
If you could hit a draw with other set of irons but not this set, it could be the shape of the offset neck cause difference in how you address the golf ball; check on this by aligning the lower grooves perpendicular to the target line. You might have been compensating by opening the club face at address so it'll look "correct" to your eyes, and open face causes fade ( one of the elements anyway ).
It could also be the lie angle, if it's too flat, then it'll promote fade shot pattern instead of draw.
If everything else is the same, I would say the shaft flex is too stiff. Use a softer flex and/or lighter weight shaft.
One of the guy told me that for his life he could not hit a straight or draw shot, always slice and occasional low and to the left. We found out he was addressing the golf ball with a shut club face ( in fear of the slice ) and incorrect grip causing a slight outside to inside swing path ( casting ). Plus a whole bunch of other issues which we will not go into.
