yes you have a point, but IMO those things matter more to the fisherman than the fish (except durability....that is a must). the only thing i could see actually affecting the fish biting would be the fall rate. and even that is a sensative thing. the way i see it, if a fish spots a lure he knows if he wants it or not. i dont think they will analyze the fall rate and make a descision based (uless it is to an extreme). most baits fall at around the same rate, and most baits catch fish. the texture and softness, well the fish has to have it in his mouth to figure those two out, and by then you should already have set the hook on that bad boy! ;D
anyway, like roadwarrior said, we are all entitled to our opinions, and that is mine
have fun fishing whatever you get
(ps. like someone said, that ebay one looks exactly like ***, you should buy from brent ;D)
