I'm new to fly fishing, I just bought an 8 1/2ft 5 wt and I love it! I talked my dad into coming out with me for casting practice and such (he's been tinkering with a fly rod for a couple years now) and found out that he's been using a 9ft 7wt rod and doesn't know the line weight or type (got it at a garage sale). I have watched him catch fish on this setup, but we fish high alpine stillwater almost exclusively. Like I said I've seen him catch fish with this setup, but now that I know a little more I've gotta believe that he'd do better with a lighter setup. What do you guys think?
