I am 74 yrs old and playing the Maltby PTM irons with the XP95 steel shafts regular flex.  Looking to go to a graphite shaft in an “A” flex.  I’ve finally accepted the fact that my swing speed just isn’t what it once was.  Heard some good things about the Paderson TS-1 shafts and was curious to know if you’ve had any experience or tested these shafts.  Thank you
