I bought the St Croix 13' 7/8 weight rod last winter and have used for both michigan river and surf fishing this year seemed to do the job.
However, I am by no means an expert on the other available spey rods in the $ 200 to $ 300 price range.
It was good for steelhead with the light 4 and 6 lb tippets we normally must use in Michigan rivers. I think it will be to light though for the king salmon bruisers and I will have to revert to my 9 and 10 weight single handers for them. Will let you know after the fall salmon run.
