RSchulz5: currently using the lvl 85 Nikes.
These are high trajectory with quite a bit of spin.
RSchulz5: I use the lvl 71 20XI balls.
These are not the slowest meter, and are high spin.
As said already (without double checking) the L90 irons will not increase your dinging. That faster meter is not for all.
RSchulz5: inconsistent distances
OK so we have good spin, high trajectory clubs with high spin balls. You are playing some high end gear. In all honesty the problem is with your shot settings. You are playing with equipment that offers great accuracy, but ONLY if you understand every spin setting of the ball and have your clubs fully mapped with them, which is obviously not happening fully?
Wind / elevation calcs need to be sound too, but if they were not that would be a cause of poor distance results with anything, just exacerbated even more with your high end equipment.
Solution:
You have very good clubs already, no need to change there, but the ball is defeating you hardware wise.
Therefore change the Nike ball to a slow meter L34 Cally. It will not be as demanding with such exact pixel settings needed (distances even with dings / separately veering off with slight misses) compared to the Nike. The L33 Cally is a great ball too but a slightly faster meter than the L34. Whatever club / ball combo you decide on stick to only that.
After that fully map your irons at Beth B9 low wind (cross wind) practice mode. Use #10 for long irons and count only dings. Personally I would use neutral spin, 97.5% BS, and 95% BS. Count only dings, and take the average of at least 5 dings per shot you want to map. #11 I would map short irons, and 12 check both again if wish. The ball change will help anyway, and then the more effort you put in to the rest the more you get back.
Pretty sure that will sort you:)...get to shooting sub 30s often, and then perhaps look at even better irons / even ball. I am a gear freak but many shoot great with that L33 Cally. Come a free rental have a look at the even higher spin R11s, but seriously doubt you want either them or a Nike ball just yet.
