I usually trade in the SHN format on high quality disks (no generics including Maxell and Memorex.) I usually use Taiyo Yuden Fujis or TDKs made in Japan. All the normal rules apply: -no writing on the disks -Padded mailers with Case Logic or Paper Cases -no fiber mailers -High Qual Disks -Source info if at all possible etc. etc. I do have quite a few Audio disks, all of etree lineage, and will trade audio on occasion if done properly. However, my Audio list (about 70 or 80 shows) got wiped out in the crash. I'm working on a new one. I write with a Plexwriter 8/4/32 with my EAC offset at + 355. That's about it.
