The University of Michigan uses sixes, not fives. I know one of the bass players, and a guy who was on the cymbol line, and they both said that they were sixes.
Unless you meant a different school, but based on your location, I don't think that you did.
I would agree with most of what multi-Thomm said, except that the brand of drums you play will determine if you can take one spock off to make fives. I know that with
Dynasty you can't. I'm perfectly happy with fives - but if you want sixes, then go ahead - just remember that it will add about 100 - 120 dollars to the cost of the drums.
