Parker said "Don't matter if that back hook is buried in the hern or not. Sometimes I do, sometimes I dont."

If you are mooching and have to cast you bait away from the boat to avoid tangles it can be useful to bury the trail hook, as it will keep the trail hook from hanging up on the leader or mainline on the cast. If you are motor mooching or trolling I don't bury the trail hook, as I believe the "Westport rig" spins tighter and easier.
