In my case, and probably others, since my grandkids broke my 1st cheap outfit, I will go with a 4 or 5 wt. My reasoning is this: if it is for your pond, as with mine, BG are almost getting to sampling size, LMB fingerlings in Aug, HSB fingerlings in Sept. Use it for a few months, then progress to a stronger one(I need something that will hold up to whatever nails my $gill pseudo fly when I tie it on. Is that a good reason to have more than 1 size flykit?
Selection of fly rods and line sizes is very subjective, and dependant upon the experience factor of the angler.
A 5-wt fly rod is the “standard” as someone mentioned, for the beginner or the expert.
The beginner WallyWorld or Cabelas combo is a slow to moderate action whereas the advanced caster would likely choose a medium fast action.
That is likely the reason Sunil feels 5 wt to be “squishy”.
Fly lines become even more subjective, and are based on the weight in grains of the “belly” or first 30 feet of the fly line – gets more complicated when interjecting double taper lines vs. weight forward lines.
I believe a 5-6 rod to be a 5 wt with a 6 wt line – Sunil’s choice of a 6-7 wt is because he is an intermediate or advanced fly caster and a 6 wt loads easier with the 7 wt line.
Many “bream” fishermen prefer 2-4 wt rods but they wouldn’t last long in our LMB and HSB Ponds.
This confusion is causing forward thinking manufacturers to grade their fly rods in “range of grains”, and the reason for the popularity of “combo” rigs for the beginner or advanced fly fisherman..
BassPro, Cabelas, and others area are solving this problem by putting together their own combo sets as TFO is doing, which are also available at the big box stores for the beginner as well a advance fly fishermen.
Probably more info than you wanted to know… IMHO – FWIW ...
