I used a high density foam... It absorbs more vibration! Paper will keep it stiff, but lets the vibration travel through easier. Did you know sound travels on the air in a wave called a frequency, and your barrel resonates on a frequency. So using foams to space (one piece is best IMO) the barrel can help silence the weapon too...
Also I would like to thank Ranger for teaching me how to make barrel spacers here... http://www.airsoftsniperforum.com/showthread.php?p=43344

OK. I will differ in opinion until fact can disprove my hypothesis though. Which is that soft spacers will absorb more sound!
