I've been testing a few balls w/ the Nike 85 irons (spin 3.5, meter 3.5)
I'm getting use to results with the Callaway 37 yellow ball (3 dis. 3.5 spin 2.5 meter)
IMO the meter may be a tad quick, 6 meter total, and a spin total of 7.
I wanted to try a slightly slower meter total, and maybe a little more stick for the Best Of Par 3 games, maybe the Pinehurst greens, so I decided to test out:
the Nike 75 ball (5 dis. 4 spin 3 meter)
The real interest was testing a slightly slower meter total of 6.5.
Summary:
Nike 85 irons + Cally 37 = 7 spin, 6 meter
(not super sticky, meter a tad quick IMO)
Nike 85 irons + Nike 75 = 7.5 spin, 6.5 meter
(sticky enough for me so far, meter just right, plus the 5 dis. for long drives)
ps I agree with what many pros have suggested that it's not good to have many different types of balls. But I am almost done in the testing phase, and it will be rewarding to get accustomed to the one favored ball as soon as I choose the right one my style.
The Call 37 and Nike are a little similar so the upgrade isn't too severe:
Cally 37 ball (3.5 spin - 2.5 meter)
Nike 75 ball (4 spin - 3 meter)
