YankeeJim:
slillico: Do they perform as advertised? NOPE
I highly recommend you drop that 81Nike ball and try either the lesser one or the 33Callaway. (The ultimate verification comes from none other than CIB-he discovered it.)
The Callaway and these irons DO perform as advertised for me. :-)
Been doing some investigation playing every ball but the wgt ones and nike 48, I'm out of those 48's, just had 2 rounds of my life with the cally 33 ball. I mean 4ft approach stat over 18 holes is unheard of for me, with 3 approaches landing at 1 inch and almost a double eagle.
Now for the tin foil hat, my early investigation is telling me clearly that accuracy declines the slower the meter. It may not be the spin it may be the slower meter that's the culprit. We may be paying more then just more credits for a slower meter, I think there may be an accuracy cost as well. But I do see top players using the max balls and still have a very good approach stat, so I'm left scratching my head here.
I just played a par 3 LW CC thing, I did ok but it was from really good putting, was using max ball and ball was flying all over the place, left right long short by several yards, but on a good note, still closer than the r11's.
So for now, it's the cally 33 all the way to the credit bank.
EDIT: The level 48 NIKE ball seems fine as well. Lots of people are reporting no issues with the lvl 81 ball though. I'm scratching my head in bewilderment on that 1. I'm unable to hit the lvl 81 ball with good precision like I can the lvl 33 or the 48 Nike. I know what I'm going to do, looks like all but 2 balls for me for a while.
Must have something to do with programming and where you stand on any given day, I suppose, tomorrow they might perform great, who knows.
But The Nikes still rock!
