I cannot get lead tape nor rubber tungsten swingweight “dots” to stay on the sole of my Mizuno ST-Z driver head. Any experience or suggestions to remedy this problem? There is not enough flat area on the trailing edge of the head where the crown meets the sole to have an acceptable application area. Is there a swingweight product (tape, dots) that adheres better but not permanently that does not require drilling the head? For those unfamiliar, the ST-Z has one rear weight that is not interchangeable nor movable.
