Re: How do you know if a line is too heavy for a rod?
Could it be that the rod really needs a 6wt line to perform well, possible that your 5wt line isn't heavy enough for it. I've fished my rod underlined once and it sucked. Possible but you really had to force it to do anything. No anyone with a 6 or 7wt line to stick on it to see if that helps.
