I'm mildly impressed at how long you've been here but yet haven't got the basics.
General DSL rules of thumb
1) Never use Piglets for drive in any weightclass ever (as JW says)
2) For batteries, 1 ant battery per spin motor. So 'BIG TEX' only needs 3 ants (add an extra if you have weight, for good luck). Burst motors still need their amp ratings fulfilled but all spin motors only need 1 ant each.
3) Realism. In DSL-S and IRL no moving part can cut through anything else. This is likely the actual reason Textanic never got accepted, as the blade goes straight through those batteries.
4) Don't use different drive motors in the bot. It just doesn't help. Dallas would likely run great on 4 NPC Fasts.
And now some more IRL directed advice
5) Wow your supports. I'd be cautious of ever accepting BIG TEX or Midland Monster into any IRL tournament because there's so little support for the massive motors and, generally, the huge amount of weight. You'd never see a real bot with 8 mags and 2 big spinning discs supported by only 1 thin pole into the chassis. It only needs to be aesthetic supports. Also, nobody would ever leave 8 mags so very exposed.
Hope this helps.
