BladeRunner is indeed a really good bridge replacement for Fender Stratocaster. Instalation is super easy, and quality is very good. There is a big BUT though.
Like all tremolos that doesn't have locking saddles, when bending g and low e strings, saddles are gonna slip a bit so those particular strings are gonna go out of tune (its because a tension of these strings are very low, so they are most critical). Of course, when you depress a tremolo bar they gonna return back in tune again.
Having said that, I experimented with lot of tremolos on my 1996 YJM Fender Stratocaster, and I have to say - pretty much all of them stays in tune quite well - original one, bladerunner, etc. If Your nut is cut and lubricated properly, if you restring guitar properly, stretch strings, etc.
I would like to see BladeRunner making vintage style bridge with saddles that actually locks and locks string in place, something like vintage floyd rose without fine tuners.
