For most river and stream conditions, if you’re going to be fly fishing, the following recommendations should work just fine.
Fly Rod Weight
4-6
Fly Rod Length
8 to 9 feet unless you are fishing a small stream with lots of obstacles. Go shorter if you have casting obstacles. 6 or 7 feet might be better.
Backing
20 pound test (50 yards should be plenty)
Line Weight
4-6
Leader Tippet: 7x – 0x (2 – 10 pound line)
