We climbed Brown from the lookout via the Knife Ridge (Class IV). The South Bowl is also another high avalanche prone area, so beware. As far as Edwards goes, the whole N/NW face was letting loose all day long the day we did Brown. Good luck if you choose to go up there, looking forward to your prospective trip report. I'll get some more beta from a friend of mine who has done Edwards in the spring, he may be able to help you out more than I can.
