I have recently acquired a set of P790s wit the standard stiff graphite shafts. My previous irons were regular flex PSI.
Here's my problem: I was very consistent with the PSIs, hitting my 7 iron 175 and my 8 about 160-165. The 790 7i now goes about 185 carry, total distance of about 195-200. My 8i, however, has stayed in the 165-170 range. The 790s are definitely longer but now I have a huge gap at 180 yards.
I think my next step is to put the clubs on a loft/lie device to check that there is only a 4 degree difference in the clubs.
Anyone else see this?
