Good irons, light shafts... do you bother?

I’m looking at a set of '71 Dynapower Button Backs. Great shape. Stiff steel shafts… but their True Temper Ultra Light. Would you even bother, guys?

The button backs are one of my favorite heads…

Really solid clubs…

pull the shafts and put is something you like… like some nice stiff X steel shafts… Hogan 4’s or the old TT #1 if you can find them in another set…

Grip em then rip em…

Are (or were) the heads not matched to the shafts though? I think that’s pinzer’s concern.
