Just looking at the nine I posted above, I missed greens 1, 3, & 8 with PW and short irons. I did better with 6i and 5 hybrid, including greens on 4, 5, 6, & 9 and a fringe on 2. No wonder I scored better from the longer tees! π
It's gotta be at least partly that the short iron shafts are too light, like @Sparky is talking about in his other thread. By the time I get to longer lengths on 7 and 6 iron, and 6 and 5 hybrids, that same shaft seems to be a better fit.
Why oh why don't I just go single length from GW to 7 iron????? Oh well, that's for a different topic.
