There isn’t a river in Colorado I wouldn’t fish with a 4 weight. If you are going to be on a boat any time on the Snake, South Fork, Henry’s Fork etc in the summer you will be outgunned with a 4...

I think this is the way, or an 8'-6" weight 5 weight instead of a 4. That being said I would not take any advice from me seeing as how I have a problem - 2 - 4 weights, 3 - 5 weights, 2 - 6 weights...
