Ibanez ZR tremolo system?

I won't repeat the technical specs, but I owned a Floyd tremolo on a Jackson, and after much tinkering with the set up, intonation, tuning etc..it performed well even under extreme tension..It was solid, I could have dropped a brick on the whammy bar and still be in tune. I have a student who has an Ibanez ZR system you mention and it seems much smoother, more flexible and dynamic. The ball-bearing system provides a friction free action Superior to the Knife edge system. It is also much easier to set-up tuning too. It's a bit like taking the Floyd and Kahler systems and morphing the good bits of technology together. Not sure about the 'gargle' trick but Go for a ZR (thumb wheel rather than Allen screw!). Ps I'm an exBathonian of 7yrs,( Marlborough buildings NR the Crescent)..beautiful City just don't be near the centre in a car between 4.30 and 6pm, walk on Saturdays!!!
