Just a note, i own an assault XX..and bent out an oar on the bulkley, which is a class 1, maybe 2 (for the people who would know (pkk, uliwon, etc) what would you class Tatlow and Telkwa stuff?) where i floated.. Even with upgraded oars, the rack and pin system is an obvious short coming for heavy water. like i said, great fishing system, but don't kid yourself that you'd be ok in class 5
