Have them on a couple Dean Caddys, an Ibanez Iceman, two Reverends (Tricky & a PA), an Explorer, a Tele and a Les Paul. Rollers vary, I use Rev rollers for the Reverends, and Tone Pro and Schallers on the rest. Best tuning stability out there and a great variety of tricks (they mimic most trems easily- I can divebomb without going out of tune like a Floyd or Kahler, and flutter to my hearts content like a Bigsby, plus everything inbetween). I do not use locking nuts, but do use locking tuners.
Disagree on the tone suck comment about roller bridges, have never had an issue.
