Matt - Single pleated pants can really go either way. You're tall enough so that the shortening effect of cuffs is irrelevant - the remaining choice is a matter of personal preference. Personally, I prefer no cuffs. In fact, I have a black three button with single pleat trousers and I have left them uncuffed. As you likely know, cuffs are considered a bit dressier than non-cuffs, but with so few men wearing suits at all these days, I've never felt under-dressed with this suit. Because the fabric is not very heavy, I had them add a heel guard - an extra piece of fabric sewn into the inside of the cuff - to add weight and drape. As a tangent, which may be moot as you've already bought the suit, I would be careful using a black suit as "all-purpose". In many places, black suits are considered acceptable for funerals or for people with more money than taste. (In fact, when my father sees me wearing one, he says "Hey there Hollywood", which I find exceptionally funny.) I like the look, and I'll wear black suit at night, but never to a business meeting and never to a wedding. Things may be different where you're from, but up here the "all purpose" suits are charcoal or navy...
