These didn't stay on the market for long, but seem to have a dedicated cult following. Personally, I can't see 1.) having to bend with my pinky or 2.) how to keep either the whammy from moving or the the rest of the strings from going slack during a bend. It's not unusual for strings to go slack when bending on the fretboard with some trems.
P.S. Note the name change but still the same ol' Wyatt
