So I am looking at buying a 6 weight Spey as a kind of all around spey. it is 12'6". I was wondering how effective a lighter rod would be at throwing Semi-Large intruders and marabou patterns for winter fish? I know a larger rod would be better, but I also want a good summer run rod. Does anyone here use a 6# spey for winter fish? It will be coming with a scandi head, but I am also looking to see how well it will perform with a skagit head and sink tips. Any input is well appreciated.
