Another option other than cutting off the downward facing hook off the trebles would be the use of a hook with an inward facing point. A look like the Mustad Triple Grip, or the KVD Elite treble hook have points that angle towards the hook shank and they don't hang up nearly as easily as a standard treble does. Beaked treble hooks are also another option. Personally I'd never cut a point off a treble hook just to make it less snag resistant. Especially not off the belly hook.I saw where a fella would snip off the forward facing hook of his treble hooks on crank baits (both front & rear) to prevent snags. I've never tried this yet but sounds like it could help. You can always replace the hooks if it doesn't work.
