Best staggered height split post tuners for US Strat?

noisepolluter

I’ve concluded that the modern style Strat tuners really aren’t for me - my ‘99 Schecter US Strat has a really nice set of own-branded staggered height split/safety post style tuners which have been rock solid for 25 years now so I’d like to get something as close as possible for the fender. I’m guessing the Schecter ones are either Kluson or Gotoh. 

Closest I can find seems to be the Kluson Supreme staggered set which has an 18:1 ratio and would need (I believe) a set of 10.5mm conversion bushings as well as some extra screw holes drilling, for which task I’ll be recruiting Estheroid obvs.

Have I overlooked any choices? Am looking for the finest ratio possible as well as staggered height, and availability of suitable bushings.
