Dober, my fav way to take the Y bones out is to pluck em after the fish is cooked
I really never understood what the big deal was with them. If you use your fork to split a fillet at the mid point between the top of the back & the belly you expose all the Y bone ends & you simply grab them & pull em out. You can grab many at a time & strip that fillet of it's bones in a matter of seconds.
