Frank,
You're right about that excuse for a new kit, but fortunately the Big A already sent me a Panther to put 'em on!
I wanted them because I plan to build that "Black Knights" beastie as the APG example, complete with horribly rucked-up tracks that the nice DS ones just can't replicate. (I know, anything to avoid adding Zimm...
