Well I'm glad to hear that HA will have a first class section on their new planes.
There's nothing notable about HA's FC, other than what you'll miss -- the old 10's which are really old. They still have a single movie screen for everyone. When's the last time you saw that? If you are looking for CX quality -- forget it.
HA is notably a vacationers' airline. Most are looking for the cheapest fare to HNL, so the first class section is used as a safety valve for oversold coach. The pax are happy they're going to Hawaii.
In a way, I'm going to miss the old 10's. They're like old shoes, worn but comfortable.
Have a good trip.
