I've seen some people buy 8 shots of his sheriff/guardian for 800. I've also seen light shields and 4 shots. Some people go the slow trap with a mix of both. What do you guys think?

This is obviously not a common occurrence, but every once in a while, people like me (smoke main) are forced to fill duelist roles. I have no problem doing this, but it's not my natural role, as typically I'm a slower player. My question...
