Our standard graphite shaft for the AP1 irons is a low balanced shaft and as such, it swingweights out almost the same as the lightweight steel shafts.  We have a small range of head weights but only use them for a change in length, unless a swingweight is requested. 

Hi, It would depend on how much the steel shaft weighed and which graphite shafts.  If you are talking about Kurokage 65 Stiff flex shafts and XP 95 Stiff flex shafts, the swingweights would be within 1/2 swingweight.  If you are talking about DYG S300 (std wt) and Kurokage 65, the swingweights would come out within 1-2 swingweights.
