When I first began fly angling, I acquired a 9 foot 5wt, a normal trout pole work horse. I fished it for a while however really did not have as much enjoyable fishing for the smaller fish that populated the creeks near my house. So I purchased a 3 wt. rod. This was the beginning of the fixation. Simply like picking a golf club for the shot, you have you select a fly rod for the fishing conditions. This made my fishing encounter a lot better!
Several years have actually passed as well as I'm still contributing to my collection. Spey poles, switch rods, Tenkara rods simply among others. And also that's just the graphite collection. I still have glass and bamboo to expand into.
