The word from a top member told me that the NIKE RZN (L61+) 3.5 spin ~500c are consistent. (more so than similar balls that are more expensive) Now, he plays w/ the Nike 97's irons w/ spin of 4.5.
Individual results may vary. In my opinion...
I've just figured out that spin means a lot when getting yardages correct.
I find that if my G25 L59 (HIGH traj. irons) or my Nike 85 irons (spin of 3 & 3.5) are matched w/ a ball w/ spin of 3.5 then I have good results with how I hit and calculate.
Balls w/ high distance ratings seem to get extra distance (say in no wind) esp. OFF THE DRIVER and with a little or moderate top spin (generally, say, in no wind)
A ball with high distance rating with a big tailwind will really go far with some BS because of the higher traj. so the tailwind pushes that puppy real far, WITH THE DRIVER.
(it all depends on how hard the wind, and how much BS)

But if you have those 'speedblade' 75 irons w/ spin of 3.5 and use a ball w/ spin of 5, that throws off your trajectory and adds a challenging spin to the ball, unless you have experience w/ how to adjust your spin dot proper.
Those TM ' speedblade' 75s may be better w/ a ball w/ a spin of 3.5 (maybe even 4.5) but the yellow callies I like or the nike balls or callie 33s w/ 3.5 spin, or maybe other balls of 3.5 spin because my irons are PING G25 and Nike 85 irons w/ 3 & 3.5 spin.
The extra distance I note on drives and I'll use a little TS usually for extra distance (it depends) but if there is a significant tailwind THEN back spin will cause a long drive.
(frontwind & BS causes a shorter drive than if using neutral spin, from what I've seen)

See, here below is a Nike red vap 42 ball (700creds, gifted to me by WGT) w/ the G25 L59 irons.
The balls have the extra distance rating of 5. Off the drive, with proper spin: BS w/ tailwind or a little TS otherwise, generally, gets the extra yardage off the driver. I don't really notice the extra distance applying to the approaches.
My calculations were spot on 'Average distance to pin' about 5-6 feet. I usually never get that during my games. Maybe it was just a lucky streak, IDK
