I rarely use anything with a floating bridge or locking nut as i don't like them too much, however as far as they go, this is probably the best iv'e used, solid bit of equipment, had no issues re-tuning after use and the screws slide in very smoothly; holding the strings in place without issue, if you do have a floating bridge and locking nut then this is nut to get as it doesn't fail, at all.
