interesting thing, guthrie govan's new sig model charvel, has an old school floyd rose bridge..
like the original, with NO fine tuners...
but no locking nut..... just locking tuners.
the only reason i could see for having a bridge WITHOUT the fine tuners, would be if the strings were pre-stretched and would not lengthen from the use of the trem..
and even then, the idea that the string should slip thru the nut with the right setup, kinda negates the downside of no fine tuners...
i use Kahler trems, and have for 30 years, have soldered the ball end of the string, from the first twist all the way up to just short of the bridge saddles, and this keeps my guitars in almost perfect tune (relative to compensated) with heavy bar use
