If you are 6'5" a flight in a CRJ2 will be quite unpleasant they are very very cramped. Plus the overhead bins are very small, which means more checked baggage and fees. I personally don't fly go! because I have a lot of family and friends who work for Hawaiian and I like to support them. One thing I have noticed though is whenever I look at the departure boards, you always see a lot of red "delayed" notices on Go/Mokulele flights, I think they've had some issues with on time preformance recently.
