Danny,

I've designed some 100MHz drivers using that device, and 
I've always had to use individual bias adjustments for each 
device. You could sort them with a current meter and a 
variable bias supply and probably hand select pairs.

You'll never guess what else I use that device for! Receiver 
amplifiers and mixers. They make darned good high dynamic 
range amplifiers and mixers for HF. You can easily get to 
the point where IM in good crystal filters limits receiver 
performance with them.
