Hi, I have a set of Ping G410 Irons with Alta CB red graphite shafts in senior flex, they are much too soft for me.  What would be an equivalent graphite shaft I could use in these heads?  I’m currently playing Ping I20 irons oem graphite stiff, soft stepped x2, i.e. five iron shaft in 7 iron and would be looking for something similar in how they play.

I tried an NV Comp 85 iron shaft I had sitting on my shelf, soft stepped x3 , way too heavy and stiff.

Thanks!
