MO'COOL Cab choice?

I am debating bringing a 2010 Chateau Montelena Cabernet Sauvignon The Montelena Estate (while I have a 2005, it apparently needs more aging than the 2010) or a 2007 Cain Five (Meritage blend from Spring Mountain District) 2007 being a good vintage in Napa. Those attending MO'COOL want to weigh in on which I should bring? Is there a chance of a Chateau Montelena mini-vertical? I was also considering a 2007 Larkmead but I like it so much and since it is my last bottle of three from the vintage and no more showing to purchase on wine-searcher.com, I woud want more that a few tastes of that one.

JC,
This looks great! Any chance you could put that on FB? A lot of members are discussing what to bring and/or building verticals.

One WEEK!!
