Heya Ken,
All area's of Hinze will produce fish
From my experience the Western Arm seems to produce better quality fish and is great for lure casting, the Eastern Arm seems to be where I catch plenty of littlies.
I've also had days where the North Eastern section around from the main boat ramp has produced nice bags of quality fish.
For your first trip I'd be checking out the Western side, it fishes well and the scenery is great
