Debating as to wether or not to sell off some of my herd and going for a 600 . Anyone experiencing the loose shaft wiggle or balance issues or any other issues ? It seems a lot of folks either love or hate the new Nox . If the ID is not that accurate , that's no big deal to me as I go by sounds anyway . Also , is anyone experiencing getting fooled by those deep iron " iffies " very frequently ? My Explorer SE plagues me with that .With the onset of old age I don't really appreciate deep digs for rusty nails . Any input from you Nox would be greatly appreciated .Thanks .
