I agree it should improve your hook-up and landing %, but personally both fish I've caught had the entire bait in it's mouth and the top hook was all that was really needed, they weren't getting away. But that won't always be the case.

The few times I would remove the bottom treble hook would be fishing through heavy cover and fishing from shore,especially around rocky areas. The lure sinks fast and you are just bound to hang it up.
