Go for the HR, then you wont have to upgrade later, unless your planning on going for HC later, then you'll have to redo it anyway.
Got my HR licence about 10 yrs ago too, about as soon as could after coming off my P's, although mine costed a bit more since I had to hire their truck to as well, all up I think it was about $1000-1200 for a few lessons around their track, out and about, and the test. It was good because the one I did took you through securing your loads properly as well.
