Callahams guitar parts explain a fair bit about the differences between various Fender six point trems, along with generally explaining why and how to make them work - they do work, and you can get them to work really well, but they are not a Floyd Rose! I spent a bit of time fiddling with a friend's
Suhr Standard, and with a traditional Gotoh trem, Graphtek nut and locking tuners, she was a very stable guitar.
The more traditional case hardened bridge plate and separate block is the one that works - Fender's one piece, cast monel-metal trems from the seventies sucked very badly indeed, and they have almost no hope of staying in tune, no matter what you do as the metal is so darned soft it can't hold the knife edges in shape!
