The best trem by Kahler is by far the Steeler.

A basic Floyd copy but with couple of really good modifications.
The saddle bolt was flipped upside down and the slot is in the baseplate making the blot stay in the correct place in the saddle. Also adjustable normally from the top like an Allen grub screw but it was a left hand thread bolt with a flat head adjusted from the bottom "genius."
Then we made the radius using steps pressed in to the baseplate making all the saddles the same.
All built from hardened steel and fantastic quality.
