I’ve been playing (what I think) is the equivalent of Robin Arthur’s Classic iron series shafts — the maroon colored (parallel) shafts that you offered a few years ago. There are apparently a few taper-tipped shafts left over from that era in the online database.
Looking through The Golfworks current offerings it seems there is really no moderately priced iron shaft (perhaps $30) with 3 degrees of torque or less. There is the Prolaunch Blue ($35) but (to me) that shaft feels soft.
The MPF Pro Series comes close to the AXE shafts. It’s a little less expensive but also a little bit higher in torque. (I wonder if Robin is a supplier for this series. The testing protocols match.)
Any thoughts to selling Robin’s shafts through the Golfworks? I feel like there is a gap that could be filled — slightly higher price and slightly lower torque than the MPF — basically a firmer feeling Prolaunch Blue. Would the difference between the Classic at 2.9 degrees and the MPF at 3.3 degrees be discernible?
I feel like your TS-n irons are premium and should be matched with a truly premium low-torque iron shaft, but I can’t see paying more for the shaft than the head. I also think the Golfpride Tour Wrap 2G grips would be a really great choice for a premium club pack. Some of the advanced players in my area agree. It’s really tacky and rather durable.
