I could be mistaken as I'm not longer into building rods like I used to... but as far as I'm aware North Fork Composite blanks are made in Washington and was started by Gary Loomis. I have about a dozen of their blanks that I have built rods on, and I find them to be comparable to the couple G Loomis rods I own. (I would also mention that Rainshadow is my favorite brand of blanks to build with and is definitely worth a look)
You are right on, North Fork Composites is the company Gary created after he sold G Loomis. His high end blanks from North Fork are comparable to or exceed G Loomis stuff they are producing now. Y'all can call me crazy but the quality of construction has gone downhill at GLoomis since Gary left, In particular their epoxy work.
But IMHO Rainshadow is my clear winner in the best blank department. The blanks between every high end manufacturer all have similar modulus ratings, resin, scrim, and blank construction etc. But Rainshadow's tapers are without a doubt the best I've built and fished with. Who ever is their rod designer is a genius.
