For those(seniors/slow swingers) on the fence about flex/HOF shafts, if you play longer drivers, go R; shorter, go Sr..
If playing heavier heads, go R for any length.
I had a NB hooked up with a Patriot shaft in R, at 46 1/2". Head weight was one of the 1st gen at 204+. That thing would load like a vaulter's pole, and unload the same. Maybe the longest combo I ever hit, and was a looker with those orange-logo shafts Rob made for Geek.(Steve thought the color was not correct though, so discontinued them), and orange/white grip.
😞....yes, I got rid of it. Because there was something longer out there, wasn't there???
