I have to agree with mjyp
Yeah, mjyp is right about 5-weights on tribs (unless you are going to keep the fish you catch)! Anything BIG and you can land 'em, but you worry 'em to death.
But it would be a great rod for trout, bass, etc. Fun to cast, and you can learn how to do dry flies on the spey. Hey, some of those Michigan streams are BIG.
