Multicam with LHe

I'm about to embark on my first multicam edit: a 90 minute concert with 11 cameras. I'd like to finish in 10 bit uncompressed (SD), but I'm thinking it would be best to offline everything in DV and then rebatch my final seq in 10 bit. Is that the best process? Is DV the best offline format? I picked it assuming I'd get the most RT and best performance from multicam. Is there some other format that might work better with the LHe? Are there any other bits of wisdom you might want to share with a multicam rookie?
My config:
G5 Quad, 3 GB RAM
Kona LHe
4 TB SAN attached via Fiber HBA
All the latest driver and software updates.
Thanks for your combined wisdom.
