Loomis does not sell blanks any longer, but Gary Loomis' new company is North Fork composites.
www.northforkcomposites.com I built an used one of his Steelhead blanks last year and it is an amazing tool. Anglers Workshop in Woodland, WA is one of their distributors.
www.anglersworkshop.com Last year, supplies were limited, but I hear it's getting better. I have some heavier St Croix blanks 8, 9, and 10wt 9' 4peice SC-IV. I have a new Loomis East Fork 5-6wt and 7-8wt reel in the box I would part with. Send me a PM and we can discuss prices, etc.
