I don't see any probs with it. I switched to the 61 RZN 6 or more months ago to where i would use it and only it. Probably about same time i hit my 500th ranked round as a legend. Would say I went from about 47 or 48 percent 1 putt to what I am now. I feel super confident inside 10 fee and anything up to 30 feet for me has a realistic chance of dropping.
Putting is one of the harder things to get a handle on IMO so just keep working at it
Not being a troll or putting you down either just giving my honest thoughts. I don't think the Nike ball has anything to do with it.
Altough I ding putt so maybe i have no idea what I am talking about
