I have a few of the original LB, and MB blanks. They were very sought after and would run you more than a few bucks. Sage had alot of interest so back by popular demand they are now available as regular items. Give Darren or Ward a call down at outfitters. They should be able to hook you up.
Word of caution however . The 3113 MB will end up running you over a grand once all wrapped with quality guides,seat and cork.
Nice rod !
