It's hard to fillet the bones out of the small ones, anything under 20" or so. Some people will grind these and make fish cakes out of them, I've canned them and have a friend that pickles it. On the bigger fish, I zipper the fillets, which is splitting the fillet length ways on the natural " seam " in the fillet then zippering out the mud line. The Y bones will be in only one of the pieces and if you use a sharp knife you can follow the bones and remove them fairly easily from the other piece. You could zipper the small ones and have one boneless piece and grind or pickle the other bone in piece.
