Considering heavy trem usage is near enough an integral part of the design spec, I see how compound would work....on the topic of radius progression through the string length, I presume that the radius would reduce itself through from the nut (10") to 24th (16") so if the taper is linear, I'd expect 12th fret to be a 14.5" radius, and the bridge to be something like a 19" radius. If so, bang on the mark there Spazzy (have a banana sticker!).
I've still to decide whether to go neck through or set (academic) but knowing the technical bounds is the first 90% of the work I reckon. I've never done a floating trem instrument before, but same as everything - can't approach it half-cocked!
On perhaps a different note - what is the practical differences between Gotoh, Schaller, Lo-Pro, "real" Floyd-Rose, etc. trems? Obviously material quality (Schaller?) and simple things such as how the arm mounts in the bridge go a long way. I can't fault my Ibanez RG1640FM's unit for that one. Pop in and pop out with no screwing around :-D
