I have experienced more noise on the smaller, usual 45 singles, but I have found that as the music starts on any of the 12" records, the surface noise is gone, buried by the music. It also helps if you have a record that hasn't been played lots of times. Lots of 12" 45s where promotional singles for radio stations, and may have seen quiet a bit of play (if you bought some used), and certainly were abused when they were not on the platter, as part of the DJs rubble. New 12" LPs are very fun (and generally surface noise free) to listen to. I wish I could afford more, but generally they are sold having 2 LPs because of the limited playing time, and those records usually sell for $50 and up.
