Reel/rod rating question
I started fly fishing this year and have had a blast. I have a 5wt St. Croix Avid, but am now looking at a 2 wt rod. My question is on the reel. I see that reels have weights like the rods but don't know how well a 2 wt rod can be put with a 345 wt reel (Fly logic on ebay is what I am looking at). Am I more concerned about the actual weight (in oz.) of the reel or that I match the reel wt with the rod wt and the line wt? I see some 2 wt reels that are 3.6 oz and some that are 5.2 oz. I am a bit confused.
