You may also want to consider a Zeagle Express Tech. I think that the only sell the Deluxe model but you can easily build one using only the components you really want. It has a synthetic backplate and you can attach a 24, 30, 35 and 44 lbs Wing to it. Zeagle also offers a ripcord (30 lbs) or zip pouch (20 lbs) integrated system that can be easily attached or removed from the system or just use a weight belt if this it what you are after.
I own the basic version equipped with a 30 lbs donut Wg and ripcord system while my GF has the basic model with 35lbs horseshoe bladder and the zip pouch system. We used ours both locally and for travelling. It is light and takes very little room.
