I started a fresh XTC game with the Yokahoma yesterday. Running Smart on it with the default set of lasers means I often get squeezed down to 1 beta EMP in the main guns when shooting fighters. Its actually given me a goal to work towards, earning enough to buy enough guns to efficiently run Smart. I'm playing legit - no script editor enabled

I should point out Smart isn't optimized for capping. It'll stop shooting right when a target turns blue, which generally works fine when shooting PBE's at them but tends to be a bloodbath when a backlog of PPCs are inbound to it. MARS has a more sophisticated cap mode where it stops shooting at a certain hull percentage for a time, allowing the pilot time for his spiel before bailing.
Personally I always edit all laser ware volumes to 1 before starting a game so its possible to achieve a full loadout with any ship. Makes the fireworks prettier, Tyr becomes viable, no downside.
