Re: New to Spey rods, potentially relocating to Seattle area.
I use a 13'-2" 7wt. casting for steelhead summer and winter. It has treated me well under an awful lot of conditions. The Skagit head with a number of different weight/length sink tips for high or fast water and a few different Scandi heads with a 12' or 14' tapered leader for low water, summer style fishing.
Pretty simple setups that make the 7wt. pretty versatile. I'm sure if I were targeting salmon I would need to step up to a 8wt. or 9wt., but no need yet.
