I'm a little late to respond, but any of those trails sound great to me. I don't have a ton of trail leading experience, but am pretty familiar with Finns and Hells and am happy to help as needed. Poison Spider was a favorite of ours from Cruise Moab this year, and Top of the World and Metal Masher are both high on the list for trails I've wanted to run.
I'll be later getting out of Denver Friday evening, so I'll probably camp at Rabbit Valley or somewhere else of I70, then get up early Saturday and meet up with everyone in the morning first thing.
