Miura IC 601 Irons custom built.....I think it was $2,300 down the crapper, then the Miura CB301, then the Miura TC201..what a fantasy ride that trip down the JDM rabbit hole was. I enjoyed all but the IC 601, but it was not a good string of Golf spending decisions on my part.
The Mizuno irons I was fitted for weren't a total bust. They were better than what I was gaming before, but I'm glad to be rid of them. The Titleist 915 and the shaft that I was "fitted" for was actually worse than the Adams driver it replaced.
But seriously, my equipment problems are far more operator error than anything else.
