Well of what i've seen, i can't really say that Predators get trained as great warriors since they are young, except for the Wolf, so far they've only seemed to be amators with averege training in hunting a specific species that is greatly disadvantaged, as in we can't see them. But since they say the ones in AvP were teenagers, i would think they had been trained for a while before being thrown into a piramid with aliens. However obviously, they hadn't been traine enough. So this makes me think that they actually do have toys and not fake weapons. By toys i mean replicas of weapons with which they play, and by fake weapons i mean replicas of weapons with which they would train, such as blunt wristblades or paintcasters lol.
