With a 4 weight in your hand, everything is possible from long casts with big streamers to subtle drops with nymph rigs.
My go-to rod for trout fishing is my 4 weight. It’s the perfect size to take down to a small stream, medium-sized river, and to even use on a lake. But, you had better have the best 4 weight fly line on it if you want the best performance out of your rod.
