Outdoor Emporium in Seattle carries Crystal ivory in bulk spools. I usually fill my spools without any backing, I run Izorline on my spinning reels and Maxima Ultra green on my level winds. During the nate season I'll do some drift fishing (in addition to jig fishing) with heavy line and don't have room for any backing on the reel. I like to 12 pound Izor on my float rods and 20 pound ultra green(15 pound leaders)on my drift rod.
