im not sure if the tines would work as they are all pretty much round in shape...wouldnt be as effective as bought rattle bags i dont think...the ones ive seen had different shaped sticks of plastic i think in them so they would clank together and some fit together and some shapes didnt fit etc...
i like the real deal....a bit of a pain to carry...but IMO nothing gives the sound real antlers do....actually just ordered a really nice set of shed from Canada a couple weeks back as i wanted a nice good set just for rattling...just cant get that sound any other way to me....
