Ring setup. I was originally pretty scared that Tri would go with the 13 weapon setup and implode my chassis, but I guess he's alright with doing scratch damage.
On the other hand, let's see how my damage stacks up to his armor:
Armour: 9 (+2 wedge)
3 damage, not bad. Better than what he's got against my chassis and especially better than the 0 damage he does weapon-to-weapon.
These weapon supports don't look like part of the +2'd "wedge" to me:
Meaning that they're 7 armor. A single hit should break them and put the weapon out of commission. Take the spin out of a spinner and you've got a 1-step plan for an easy JD.
As for general strategy, I want to be kinda-sorta aggressive. Enough so that I can conted for some aggression points, but restrained enough so that I don't get yote OOTA like a moron. Drive up until he's 2-3 feet away, then turn 45 degrees as he's about to collide. Aim for the fragile axle supports and use my disc to no sell his weapon. 11 weapon vs 11 armor (and occasionally 9 chassis armor, but it'll take a lot of hits for a KO to even be a concern. Drive a little more defensively if things start to look bad).
If I successfully kill the weapon, go in and repeatedly slap what remains of his weapon. Think Yeti vs Free Shipping.
If I don't kill the weapon, back off and try again. Stay away from walls.
