Just disclose everything. The only way you get screwed is if you don't disclose, and they end up finding out on their own. They will think you were trying to hide it from them. They don't care about drinking offenses when you were in college.
I tried the Noricas recently but they were so darn scratchy that I couldn't even get through a section because the noise just bothered me so much. I've heard that Staedtler changed the formula. It's either that or I just got a bad batch :(
