Ambivalence. I respect what it may do, but it doesn't matter. I'll shred through my crosses long before any longevity benefits will show themselves. As far as an increase in playability, that may be. Problem is that consistency is the most important thing to me. I've never had a dissatisfied customer, and I've never done a bad stringjob for myself once I got used to stringing. Put simply: if it ain't broke, don't fix it. I already do the slow tensioning and holding before clamping anyway, and that's good enough for me. If someone else wants to do it, knock yourself out.
