I do not do the VH 'dive bomb' kind of thing, so I really do not need a locking set up. I have two of the Wilkensen bridges, one on my 2002 Am Series Strat, and one on a brand new Warmoth that I am almost done with ( sprayed the clearcoat oner the "BRETTOCASTER" headstock decal tonight). Anyway, I love these bridges. You can set them blocked (detune only), or floating. Together with a nicely cut graphite nut, and locking machine heads, I can stay about 95% in tune when getting agressive with it. For more subtle things, it stays in tune very well, without the "warbleing/flutter" thing that happens with Floyds when you pick aggressively.
