Not really a peeve of mine, but makes me wonder--who cares what type of rod somebody else fishes with and why would you? I fish many brands--Scott, sage, winston, Loomis, Lamiglass, PacBay, Forecast (Batson), Orvis, Diamondglass, several no names, Fenwick, yada, yada.
Why on earth would anyone care what I am fishing with? What works for me may be totally wrong for others. I select a rod to fish based on it's ability to do what I want to do on any given day. If I plan to high stick, short line nymph, I use a 10 foot 3 weight no name rod. Throw dry flies in the high Sierras? Probably use a 5 piece SLT that's 8'9" long in a 3 weight. Chuck streamers on the Snake? A 6-7 weight Loomis or a scott I have laying around. I pick the rod for its serviceability for the job I need done.
As far as looking the part, no, I don't go out of my way to give a rat's * what I "look" like on the stream. I can put the fly where it needs to go, have pockets in my shirt where they need to be to hold the "gear" I'll need on a given day, and I have fun. If it ceases to be fun, then I'd cease to fish and sell it all.
I'll not be making fun of anything or anyway anybody flyfishes. If it works for you, that's all that matters.
See ya on the creek.

"Should you cast your fly into a branch overhead or into a bush behind you, or miss a fish striking, or lose him,or slip into a hole up to your armpits-keep your temper; above all things don't swear, for he that swears will catch no fish."
