Scaling Combat Walkers

Hello all,

I am setting down to writing up my combat walkers for SG2 and would like
some ideas on how people are scalign them.  I am using the larger models
in the new GK line.  I am using Grizzly, Bear, Den Mother, Razorback,
Kodiak, and Black Adder minis.	I opted to use the larger minis in the
line because they seem much more able to contain a 15mm pilot.

Seeing as the scalign system is a bit abstract in the GZG games, I'm
having a bit of trouble deciding if I should classify them as Class 1 
or 2 walker.  I am leaning toward Class 2.  It doesn't help that I
haven't received the minis for some of them yet.

Thanks,

Eli
