I've never been bowfishing before, but am leaving next Friday for a weekend of fun on the water. I've got an old Bear Whitetail II I'm going to put a bottle on, and I'll of course make up a few fish arrows. What do you guys recommend as far as rest, release, and sight?

Logic tells me simple is better here, so I'm thinking of shooting fingers, off the shelf, with no sights.....Is that the best way?
