The question comes what do you want to do with this tank? If you want something that looks accurate and that you run around some then go with the metal. If you are going to battle this tank then to with the leopard tracks. The HL tracks are slippery and the leopard tracks will give you traction. I had the Kenny Kong metal tracks and sprockets on my Hobby Engine Abrams with El Mod in it. It had the HL Gearboxes with 480 motors. It looked great, however the speed was cut in half. When I went with the leopard tracks it took off and ran more to scale speed. Again it's your choice.
