Just a quick question regarding using the Cardas Sweep record, which I just acquired last week. "Instructions" are kind of sketchy-I looked at the Cardas website and from what I can see using track 2 (a,b & c) on the sweep side should just about do it for regular maintenance. Do I have that right? Assuming I play one of those (or do I play all of them) every couple of weeks, am I getting the job done or do I need to be playing much more of the sweep side of the record? Thanks.
