So I bought three of the Super Charged Red to try out. I like them fine. They don't seem to be as firm as the original PL Red I have in my 4-5 hybrids ( but I have no idea how much those are tipped or really even what flex they are), but they do lower flight some compared to the FGI plus and A flex Adams hybrids.
All in all for $14.99 they're a solid stiffer tip iron shaft. I still think I'll pick up one of the OG PL Red's and put it in one of the higher loft hybrids to compare.
