Sort of like firearms, one can not have too many rods. I think I'm only missing a 3 wt.
My suggestions:
A 2 wt for tiny streams
A long 4 or 5 wt for big water trout
And 7 or eight weight for steelhead maybe even heavier if one is in challenging wind situations on big rivers. I'm off the deep end here with several Spey rods (16 ft) in 9 and 10 wts.
Tight lines and stay dry,
