I have a friend who got into YLS (and many other T-14 this cycle) who would be interested in helping you. His driving belief is that the conventional wisdom on softs is way off, since he got in on a 171 and what would be labelled T3 softs.
Not unless you were convicted of a misdemeanor/felony or the ticket was a criminal offense. I saw one that stated "traffic ticket over $200" - so if they're asking something like that, make sure you are being truthful, otherwise you should be fine.
