What line rating did you end up using? I've always thought albies were hardware shy but if they went after a fly near a split ring, it sounds like wouldn't care if you canal gear (20# mono and 50# leader) on them :-)
I use 20# lb power pro tied directly to the tin then 25# mono to the fly .I dont use any snap on , I dont want to lose a fish becouse some swival breaks ,I tie directly to the lure . I take out THE weak links ..
