The greatest 13' 6/7/8 rod I've tried so far is Burkheimers 7133, but it is expensive. If you can afford it I'd call CF Burkheimer rods. Otherwise, give Bob Meiser or Gary anderson a call. I see you're in Oregon. Bob is in Medford, Gary in Gold Hills, I believe. The most knowledgeable folks I know of in Oregon for off the shelf spey gear would be The Flyfishing Shop in Welches.

If you've never tried it, you should pay for some lessons from a good spey casting instructor and make sure he/she brings several rods with a few different actions. It will be money well spent.
