I just use a Shakespeare Prius ultralight rod and reel which is 4'6" with 2-6 lb test line in small streams and larger streams I use a Berkley Graphite Cherrywood light rod and reel 5'6" with 2-6 lb test line. Even in lakes I use the Berkley Graphite Cherrywood light rod and reel since its a very good larger water light rod.
I think its mostly dealing with presentation of both the lure and bait.

Like go to website to find more trout fishing tips because theres loads of them out there.
