i think they look retarted. just get a chatterbait lol. also, i dont like how the plastic bill is infront of the hook. i know its supposed to fold down, but i still dont like it.
my only guess for the size of the bill is tht the larger one will produce more resistance, therefore more vibration...
on the original rad lures chatterbait, the skirt is molded together so its super easy to remove and replace, so you can just slide it off in one pice, put on a fluke, and there ya go. or you could leave the skirt on and still add the fluke for more bulk. tahts how i fish my chatterbaits.
