I’ve cut some Project X – flex 5 shafts for my Maltby forged heads – BUT – I did not follow the trim code of IR2 – rather than that I simply trimmed from the butt of the shaft. These irons are for myself. How badly have I screwed the pooch on this one. The shafts are flighted and fairly expensive. I’m thinking I’m going to get a softer regular – but that’s just a guess. Thanks all.
