When a reel is rated as a size 5-6 is it that just a recommendation or a hard and fast rule? Does it just have to do with the amount of backing you can get on the reel? For example, if you have a Lamson Konic 1.5 for 3/4 wt lines, can you put a WF5 bass taper line on it and just reduce the amount of backing? What about going up to a size 6? Seems to me that I could use a smaller reel and help reduce the weight and just put a heavier line and it could be cheaper buying a spare spool instead of a new larger reel. Any direction on this is greatly appreciated.
