I hear ya, the Mars pattern Warhound is easily one of the coolest models out there.
Hey, and a great idea with the CD's. Probably the best and easiest way to go if the model is meant to be used on the table. Those huge bases must be quite annoying to move around.
Hmm, or perhaps some metal disks for extra weight, or do you feel that the support the give would be enough for the model?
