I'm going to have do some reading up on this stuff but when you guys talk about 3-4-5wt. 2 handed rods those lines are not the same lines I'd be using on my 7'6" rods. You talk about shooting heads and such and weighing lines in grains of certain weight and none of this makes sense to me if they rate the rod at a 4 wt. That should mean I should be able to grab one of my reels with a WF4F on it and go fish but doesn't sound that way when you talk about lines.
