I'm a Rio guy and I never really have issue with thier products. As for floro, I have used it, I don't anymore as I found it didn't make a noticable difference in my catch rates. I wouldn't use floro for dries because the floro will break the surface tension and sink fast generally pulling your fly down with it..... at least I have found that in my experience
Frog hair is nice stuff I've tried it, i think it's pretty $$$ for terminal tackle
