Yours look diff then mine. the spots on your are all on the bottom mine are spread out over the body. here are sum pix. One is about 12" and the other is about 7-8inch
sorry to hear to hear your clown knife loss... personally i'd choose a royal knife, just for the simple fact that they are more rare and uncommon than the clowns. Unless, of course... you come across a reg. clown that has something "different" about it?? like a different distinctive spotting pattern, for example. But that's just me. GL with your decision!
