FR-type tremolos not requiring removal of balls from strings
I'm interested in one thing concerning Ibanez Floyd-Rose-type tremolo bridges which I hadn't been able to find enough information about: does any Ibanez Floyd-Rose-type tremolo bridge which doesn't require removal of balls from strings while restringing exist? Or is it possible to restring any Ibanez Floyd-Rose-type tremolo bridge wihout removal of these balls from strings (deeper string holders etc.)?
I've found that Edge Pro "features a novel set of saddles with integrated string locks and string holders which do not require removing the ball end of the string at the bridge side" (from: Ibanez Wikia), but I haven't found any such information about other Ibanez Floyd-Rose-type tremolo bridges. According to that "Edge Pro is evolutionary redesign of the Lo-Pro Edge" (ibid.), I conclude that Lo-Pro Edge requires removal of balls from strings, but what about other Floyd-Rose-type tremolo bridges?
I'm especially interested in Floyd-Rose-type tremolo bridge which are or were mounted in Ibanez S series: ZR, ZR-II, Edge Zero, Edge III, Edge Zero II.
Maybe it's not a crucial feature of tremolo bridge, but it has some influence on overall convenience, and there is very little information about it in avaiable literature.
Thanks for any information.
