Check the weight ports on woods and hybrids. If you can see inside the head when the weight screws are removed, it's easier to add glue "strategically" inside the head.
Ralph Maltby makes the KE4 ST-1 driver head, and I was able to remove the weight screw and put the glue inside.
If you're also getting a reshaft, the clubsmith can squirt glue down through the hosel before the shaft goes in. A good clubsmith can computer fairly accurately how much glue to add depending on how much the shaft is cut. Also, you can re-establish swingweight if you trim the shaft, and go with a lighter weight grip than the original.
