Lines for Steelhead

I am going to Michigan in November, and will be fishing for salmon and steelhead. I need to outfit my steelhead rig with a line, what recommendations do you guys have. I will be using a 7wt 9'6" rod with a Battenkill Mid Arbor IV (7-9wt).
Go to AATF, Ron or Brian will get you sorted....fwiw I cast tips off of a Rio versatip or an outbound floater if I'm being too lazy to switch lines, and I get into fish so....
