I don't know about the best, but I use a 2/0 hook, run the hook through the tail from the underside right where the fins end, then around and through from the underside through the tail right before the body, then through the top of the back. rotating out throught the head between the eyes. After snugging it down just a bit, take a half hitch around the tail right at the fins.

Make sure it doesn't spin. Sometimes you want to trim the fins at the end of the tail.
