Re: Strat players, Vintage or Modern tuners?
I love the trim, classy look of the old-style tuners. And now that they are available from Gotoh with locking mechanisms and/or post height adjustability, they are pretty much modernized in all the ways that count, without having to accept the less attractive looks and weight of most modern-style sealed tuners.
I won't bother converting a modern headstock to accept old-style tuners, but if I'm spec'ing out a neck from Musikraft or wherever, I order it with the old-style 11/16" holes, and get Gotoh vintage style Mag-Lok H.A.P.s.
If I am improving the tuners on a modern-style headstock that has the bigger holes, I usually get sealed Hipshots with the butterbeans, or Sperzels with the optional small #6 buttons.
The modern-featured Gotoh vintage versions go on new builds only. I don't swap out stock Klusons on my Fenders for locking, height-adjustable ones. I just use them, because they are fine. I do, however, use a standard self locking string wrap on them, though, even though they are slotted and center drilled.
