Doc and el3,
I had not focused on the hand eye bit - i did miss that.
..................The hand eye bit I can grasp. I know a couple of years back I was out football (soccer for you guys) training with him (edit my son). The ball was coming at my right side and I naturally went to get it. All good so far but it just sailed past me LOL..........The mind was there but the body never reacted as it did once. Similarly I also now use reading glasses..........
Obv I don't know exactly what your particular issue is, and you are obviously the best judge of that. All I would say is the numbers WGT give out seem guides rather than this paired with that = exactly that. Never studied it hard but basically try the L90 irons if not. My guess is that with a L33 ball they would be too fast for you. Maybe a HL ball would help but that's more expense. Speed aside transitioning from the L90s to the L97s / 100s is a breeze as it's mostly covered off with the L90s (spin / trajectory), but that's pure line and length of flight. The L90s don't even give more forgiveness than the L85s, and so if it's ding control probably best looked past. The L85s can allow great scoring, just get to that long approach at CCC 18th say and that L90 3 iron will be best (one example with speed aside).
I have about 70 RR since tiering up - probably at least 60 go towards saturation
EDIT:.............If that's the confirmed case post update you are ahead of me. It was 500RRs at L and (check this bit) a threshold of 59 to tier up to TL (for whatever difference tiers make now of course).
