Alrite, lets get serious here man.
You live in NZ, a lot of people on here do not, get yourself down to your local shop and ask the people working there how much the hell bent is and do the same for the ARG. You are really lazy.
The ARG is way too specific for NZ in my mind, unless you are doing a lot of heli drops, are you?
If you after a resort pow ski that will occasionally be hiked/heli lifted then i would get the Hellbent, you will have a lot more fun on them and they are way more versatile.
ARG - Stiffer big mountain charger
Hellbent - Playful, versatile pow stick that will take you everywhere.
Take yourself seriously, just because you got dumped on a couple of weeks back do you really need this much of a ski? The new obsethed would work better and has a 25/20 rocker i think, which is plenty. You should be able to buy it now, as NZ gets K2 before everyone else.
