Just reshaft a 5 iron using the Aldila NV 105 S a couple of days ago. Did not like it. Too whippy.
Gonna change the shaft back to steal , not sure which one, but I'll find the right one. The 6 iron has the OEM light weight steel and it played fine. Darn this warm temperature..... I was thinking of shafting the R flex light weight steel a few weeks ago for the Winter months.
