I went in the Dore two seasons ago and like others have said, it isn't for the faint of heart, lots of technical spots but TONS of riding area (I ended up trashing my sled's hood trying to get over to another glacier). I rode 165km in one day in the Dore area, pack lots of gas and hire a guide if your going to do it. Also get your avalanche training and be aware of cravasses. When I was in there, about a month earlier a guy fell down a cravasse and was killed.
PM me if you need a # for a guide, I know a guy who can probably help you out.
Hope this helps
