Stone Temple Pilot

Hello! Its my birthday next weekend and I am planning on visiting Moshulu, but cant decide what is the best night. I went on a Fri a couple months ago and enjoyed it but it was a lot of new music. I know on a Sat they play older stuff, but I like stuff circa 1994 - Seps, Fear Factory, early Korn, etc. In your opinion, what would be the best night? I have a friend "flying in" for the occassion, so it has to be good!!
