Crunchy rails are considered **** from the few reviews I have seen of them. The power rails are regarded as being very nice though.

Yeah i wouldn't get the crunchy rails. It says their midrange is relaxes which i think they mean relaxed lol. So if any pickups are lacking midrange i would not get them since the guitar needs its mids to be heard well. I've got the power rails in my bridge and it is pretty sweet, not sure how it would compare to 100 dollar pickups but i don't think its far off.
