I always used a red band and ran the band at 3 1/2 turns from snug. I had some problems with a front pump that was not giving me enough pressure and was eating bands and drums. You need at least 170 lbs of pressure according to Coan. I use a Kevlar band on the steel drums. I would only use an aluminum drum if you are trying to get that last .001 or .002 to set a record or a class run situation. The steel drum does not leave the gray mess in the pan either. The lightened steel drum from Coan is a good alternative.
