For streams that you can wade across to maybe those a little bit larger that you cannot wade across- generally open casting room but sometimes you have to watch the trees- for your 10-12" trout as the average fish. Dry flies and nymphs. I sort of like a 9' rod because I think I can cast better and keep line off the water in certain circumstances- in any event- I like a 9' rod. For those that have fished both #5 or #6 wt rods- which do you prefer?
