Guided with one several times including on Clear Creek and Gore. Called it the 'barn door.' Seemed super solid - but heavy and not terribly responsive in the water. I think that there is a fair degree of brand recognition - but mostly by people that have been paddling for 5 or 10+ years. Don't know anybody that loved them or hated them in particular. Not sure I would pay much $$ for the rights to the name.
I use norse paddles exclusively in my canoes. I've got 4 or 5 of their canoe paddles ranging from the bread board (extra long blade) to shorter length regular blades. I've used some of those since i started paddling canoe over 10 years ago. they are becoming pretty hard to find though.
