>>2597829You are getting way ahead of yourself what if you don't like fly fishing? There is a reason you can get brand new 1000 dollar rods half off ... people buy them thinking they are going to love it and end up never going and selling them cheap.
Generally when it comes to fly rods people usually buy odd or even weights. So if you had a 4 the next rod purchase would be a 6. For the fishing I do I have an 8 wt and a 10 wt with the 9 wt being the equivalent of a 5 wt for trout fishing.
The clearwater is a good starter set up. If you have a lot of casting room a 9' 5 wt is the best place to start for trout fishing. If you don't have a lot of casting room you will get frustrated with a 9' rod and you may want something a little shorter.
