something you made would most definitely be the way to go. i dont know if your a songwriter, but maybe something that you crafted and put your touch on would make for a better momento to take home with you, rather than a solo over a bt or whatever. but then again, i could be wrong...if you know what you want, then disregard my advice. haha. i would just love to get my voice under some quality mics and vocal software, thats all. make the most of the opportunity and whatnot.
