It definitely looks like the Haslab pack. I've got one and the motherboard of the pack has the same curved edge. I think for afterlife the packs the PGs had were maybe from someone that builds them amd the heavily modified. Probably same for what Pheobe has. She has back problems so the Hasbro one was likely better in terms of weight for her.There's a debate about it going on at gbfans about the height, the foal roll may be bigger but to me it still seems to be sitting lower than before.
Hard to tell if it is a haslab or not as they are the movie props. Would be a bit odd for a movie to use those, as they generally make them from scratch. Though the trap field at the end of afterlife was all store bought traps so maybe they are. Probably see Adam Savage delving into it at some point and seeing whats what.
Yeah trap field was spirit traps.
