The Voodoo is described as the following:
"Innovative design combines advanced performance of a wing style BC during the dive, and the armchair comfort of a front-adjustable jacket at the surface. Incorporating a patented design, the diver can open a valve from the wing into the separate front bladders, add a small quantity of extra air, and float in comfort."
So, long story short, back-inflating bladder paired with jacket-style BCD design, with valves that connect the two. In my experience, scuba dollars work best when you purchase an item that is designed to do a job well. When you purchase an item that does many things, it tends to do all of them poorly. I do not believe this BCD would make a good travel BCD, weight-integrated BCD, back-inflating BCD, or jacket-style BCD. Also, while the inflator itself does not appear to be problematic for servicing, I do not know enough about the valves that connect the back bladder to the BCD to hazard a guess regarding servicing. This is something I would bring up with the dive shop.
My advice would be to dive more with rental BCDs, whether they are back-inflating or jacket-style, and decide what your style/comfort level is. You may also want to seriously consider a backplate/wing setup.
