In the past as a 1P or less I never had to think of upgrade instrument on LAX-HNL (2556 mi arrgh) so 6 e500 it was...

Now that I have CR1s I am hesitating to make a call - which one to use? Either one should clear (flights are on 762s) and the expiration is similar. I travel with my wife so it's 12 e500s vs 2 CR1s. e500s come from both of us, CR1s are my responsibility.

Any thoughts on picking one over the other?
