I tried them out a few years ago, and honestly wasn´t too fond of the results. It was IMO detrimental to the tonal response, most likely due to the addition of a third material to the joint, almost universally increased bite but lowered sustain in the cases I tried.
And to be honest: if your neck needs removal so often that the holes start to strip, then the Guitar is most likely a POS in the first place or a parts beater that gets reconfigured every other week.
On a good guitar, the neck screws need to be setup once, maybe twice, and then they´re left alone for the next few years at least... I honestly can´t remember the last time I had a bolt on neck from one of my instruments removed from the body...
You can cinch them down tight as all hell before the threads give, and that may increase sustain minimally due to the increased pressure....but by doing so you´re causing damage on the other side of the heel by forcing a blunt object (neckplate, bushings) through the finish, crushing it and the wood below it, so where´s the point
