I am curious about the First Run Pro Avairs. I just picked up a few and I am liking them as a putter. Why do you think they never caught on? Around here it is either JKs or KCs. The First Run Pros Seem to be somewhere in the middle between the two in regards to flexibility. They do seem to wear a bit faster than the JKs or KCs, was that the issue? When were they produced? Was there really only one run? The flight plate does not feel as thick as the 5X JKs being produced now, is that the case?
On another note, why did the JK Avairs become medium stiff to stiff in the late 4X runs and 5X runs. Is it possible to run more flexy JKs again? If so, I would like to let you know that lots of golfers in the Pacific Northwest would love it if you would. In the mean time I will keep hoarding my small stack of flexy 4Xs and hoping that I can pick up a stack of super flexy 5Xs to practice with. Thanks for your time and for all you do Dave!
Sorry, I don't remember the Pro Aviars unless they were a prototype for the JK or actualy Pro Driver material. If they were the Pro Driver material, we went away from that in all models except drivers as they weren't very popular. The drivers, on the other hand were very popular.
As for the JKs now: we run JKs as soft as we can without incurring molding problems. Usually that means a medium soft. As we go softer, we start to get warped and sunken flight plates. We are currently running JKs in medium and they look really good. We will try a softer batch, if we can, and maybe color code it to mark it.
