I bought some just to see what all the hype was about and initially didn't have high expectations of them. Upon using them this weekend, they worked for everything. Can't say I've caught many gills on similar baits (Rippin Raps/minnow mimicking hard baits)...The 1/16th Z Vibe I used caught fish...Maybe it's the slow flutter. I don't know what enticed them but it worked good for me. Only complaint is it takes a while for it to get back down there when on a hot school of fish (Slow fall may be what entices them however)
