If you look them up on True Temper or other comparison charts you will see them listed as light weight, low flex point, high ball flight irons. I have played with the R300 in the past and liked them. I currently am in graphite for my arthritis issues. As most people on this site will advise, don't get too hung up on shaft assumptions and instead, go to a fitting session and see what combo works and feels best.

I am not sure of the techs of the shaft but I am a notorious low ball hitter. So, I was looking for a shaft that would increase my launch but still feel good. I was fitted for a set of AP1 716 and went with the XP 90 S300 shafts. They gave me a higher launch than I was getting from my previous set. I am a 9.4 handicapper so we are in the same handicap range. Hope this helps some!!!
