First of all, respect for just going out and opening (what sounds like many) sets on your first night. You will definitely go a long way fast if you break your approach anxiety.
Ok, like I have been taught I pretty much always use a FTC either before or after the opener depending on the nature of the opener. For example, if it is a fairly ‘in depth’/long opener like ‘jealous girlfriend’ use a FTC before so they know your not going to out stay your welcome. Shorter openers on the other hand don’t need a FTC at the start but, in my opinion, you should nearly always use a FTC before the next conversation begins.
Try and remember body language. This is so important. My recommendation is to read up on it now if you have not done already.
Ok, concerning what to say next – a really nice and easy one is the ‘best friends test’ from Style I believe. Here is a link.
