If your lucky, canopyboy or jsweka will chime in. As I recall they have both posted reverse handle ASL's they have made.
I haven't been on much lately and just saw this.
Here's how I build one:
16" riser
0.050 glass
0.005 total taper to the lams
1 1/8" width at the fadeouts, maintain this width 14" out each limb, then tapering down to 1/2" at the string grooves
My form is perfectly straight and I end up with about 1/2" of string follow after it's been braced for the first time.
If your form was straight and you wanted a 66" bow that pulled 50 - 53# at 28", I'd suggest a total stack thickness of 0.500". If you want it reflexed, I can't provide much advice because it will really depend on how much reflex.
