Welcome to the game!, Smoates.
And welcome to the forum, it's plenty of good stuff here. I'd say to you " Go with the
Mizunos!" but you'd better try some different
irons and shafts out before you buy them and go with the ones you feel better, if your local Pro agrees.
My only advice: hang strong on what your Pro tells you, now in the begining, and fight strong against yourself in the next couple of months.
Welcome again to the Heaven and Hell.
Toni.
