Red lake trail is bad, and sometimes makes you wonder what the builders were thinking about - but not as bad as some reports made out, and my only other tips would be stay right above red lake in the chutes (easier) and after you are over on the nw slope work to the right a little to avoid the false summits and make a note of where you came up the chute to the crest - it is easy to miss it on the way down.
Really nice climb - day hiked, 13 hours total, great view.
