i'm not sure why gregg didn't mention it but 16" is the radius at the end of the finger board, not the bridge, there was a post somewhere that had a calculator to demonstrate what it would be at any fret as well as at the bridge. it is a touch over 18 inches if i remember right, and warmoth (Gregg) suggests 18.5.
i'll also add that i'm a bit of a geek with geometry. i'm a machinist so i think about angles and radii as part of the job. the diference's in the cordial height between a 14" and 18" radius with the cord length in the range of the width of a guitar neck (1-5/8" - 2-3/16") is minimal. and the diference will be less pronounced on the playing surface because the board and the strings will both taper to the same 10" radius. your left hand wont know the diference. so the schaller bridge will be the way to go.
i can give exact measurements for shims on either one of the floyd bridges if you want to make it perfect.
