Poor even taking realism in mind. Sawblades are crappy in Stock, and you could be much more efficient with the batteries in Sawplate. By trading those pinks for a Black, 2 blacks if you really don't want your bot to slow slightly near the end.
Torture.. nice design, bad execution. Blades aren't too good and it's way over powered. Needs a wedge on a Snapper too.
Also, build to the weight limits.
And don't choose an armor type in Stock. Leave the armor tab alone, and you'll have armor as light as Aluminum, but twice it's strength, making it better then Steel in weight AND protection.
