Im trying to buy my boyfriend a fly rod. He wants something for small waters. He was admiring this 3 wt 7 foot a few months ago, but it was only a 2 piece and he wants one he can backpack in easy. I recently got myself into a deal with someone for an Orvis Trout Bum, 4 wt 7 foot 4 piece full flex. Everyone I talk to sais this is great, but Im afraid the 4 wt as opposed to the 3 wt is no good. Its a good deal for a rod that sells at 375. He only has one other rod, and isn't real professional or anything, but takes it seriously. Any advice? Im worried!
