Prindle 19 rig tension

I'm finally at the stage where I get to put all of the pieces of Prindle I've been accumulating all winter together, and had one more question for the forum...

Are there any guidelines for the tension of the diamond wires and shrouds on the Prindle 19? I have access to a tension gauge, so if I can get some numbers together that might help than more than the old "tighten 'til you hear a real good twang" method.

Thanks!
I'd be surprised if there are posted numbers out there, but you want it fairly tight. Not Banjo string tight, but tight.

I think Randy Smythe has a tuning guide somewhere? I think I remember seeing his article on one of Rick White's books (Catamaran sailing for the '90s).
