Haven't used the firestorm, but my hunting buddy has a western rivers Navajo. Seems to have ok sounds but lots of useless ones preloaded. The predator calls are a lot better than the crow calls. We used it for crows last weekend and it has ok volume (nothing that will blow you away though). The loop length seemed short on the crow calls as well, but we typically use his old western rivers tape caller with Johnny Stewart tapes for crows because the sounds are good and the call is loud.
