Is there a nonCX oneworld fare option in J that's reasonable and gets you over the DM hurdle?
I guess you're 110-120 CP's short..that's not too hard- just do a mileage run!
But taking a step back- I do echo eyeballer's point.."what's the worth of DM to you?"
Edit to Add: "23hr"- so probably somewhere in Asia except HKG- look at QR!
