as someone already stated, when shopping for my big fish rod, i went with 8wt
if you already have 5, i'd go with 8wt
i already had 3wt, 4wt & 5wt, and wanted something for Pike, Muskie Carp, Lake trout, and hopefully i can do trips for some Steelhead.
i went with 8 wt, (Sage Response) and have thrown some very large flies with it, and it handled them like a champ
so far the only large fish i caught on it was this 25.5" inch Carp (my first carp on a fly)
