A dilema! Here are my thoughts...(all highly subjective)
I never redeem miles for domestic coach travel - the miles vs dollars ratio is very unfavorable. It's 30k miles for the R/T in Y - vs $650 - valuing the miles at $0.022 each - compared to international J awards - which are worth roughly $0.088 per mile.
You've got enough for two J awards to Europe right now. With your 10,000 miles, you'll be 10k short of 2 F awards to Europe. (All this assumes you enjoy going to Europe in F/J. Some people don't like Europe, and others don't mind the back!)
You also say you're elite on CO. Although I don't believe anything has been announced, I'd bet there will be some opportunity to use DL miles on CO (a la DL/UA right now) - or perhaps even pool (similar to US/AA), where you could dip into miles from both accounts for one award. So, your DL miles may have future value on CO.
Flip side - if you want to break ties with DL and go out with a bang, F to HNL is a nice way to go (just hope it's not a 764!).
Enjoy HNL!
