Alternately, you could exit via the Mountaineer's Route on Whitney, or via Horseshoe Meadows.
I actually have a Horseshoe Meadow exit in mind depending on how I feel at that point. It would let me go down via Crabtree pass which I missed going through since I aborted my Mt Whitney approach this year.
The portal would be my planned exit point.
Descending via MR... that would probably depend on how I feel at that point.
