Heck, these things may be .335. I just dry fitted a .335 driver shaft and it fit but was tight.
Very surprising because these are very much advertised as iron like with shorter iron length shafts. I'm going to give them a call Tuesday.
IF they are. 335 how stiff would an R flex driver shaft play cut down to 9 iron length? Would the headweight make up for it? The 6 iron head weighs 235.
