Conductive epoxy is usually specified as less than 6:1 aspect ratio fill capable, while non-conductives are 10 to 14:1 (depends on which brand and who you ask).

We recommend to the designers "the smallest diameter that you can get away with", that will help reduce the solder scavenging into via diring reflow. unless you are planning on having them filled as Dave F mentioned.
