You really need to get the proportioning close w/o a valve (by juggling wheel cyl / caliper piston diameters, etc), then use the valve for the last 10% or so. Here's why:

The valve doesn't "cut in" - begin to work - until there a few hundred PSI of line pressure. So in rain, etc., it doesn't do anything. And, if the rear wheels are locked, the car will - MUST - spin!

Wow, thanks for the personalized response, Rick!

I guess I was hoping to avoid taking the rear brakes apart....but I guess this will be an educational experience!
