Today I Frankensteined together some Maltby TS-1 irons. Bought a set of TS-1 on ebay with some way too manly shafts for me, and a while back bought a set of Pings that had Penley IMS graphite shafts. So this weekend I did the swap, putting the IMS shafts on the TS-1 heads. The Ping install had done a manual taper of the 370 IMS shafts, but they seemed to fit fine into the universal hosel of the TS-1s.
This set also has the GW, which I am missing in my gamer set of TS-1s. The IMS are low launch, rare for graphite. Also, these TS-1 heads are 2* up, which I have been fitted for a couple of times but haven't tried until day. I think this will certainly end my streak of 46+ years without a hole-in-one.
Shocked to find the weight profile of the IMS shafts - super tip heavy. No tip weights, standard graphite length, everything came out D4-D5. I haven't tried that SW heavy in a long time.
Pics to come.
