Ok, so the irons are finally finished, and I was able to go pick them up today!
Here are a few specifics:
5-iron through A-wedge, Srixon ZX-5 Mkii heads
Shafts are Aerotech Steelfiber i80 cw in regular flex
Grips are Golf Pride CP2 Pro in jumbo
They look and feel amazing. I can't wait to get these babies out on the course.
