iTS has a lot of unique content. They've got a lot of AFR move rips and CD rips that we're uploaded for iTS and iTS only. I've found their content especially unique in terms of flac where music is ripped with .log, .cue, cd, and booklet scans. A big percentage of their rips aren't even available at What.cd and even more so at Waffles.fm. So if you aren't an expert CD ripper you could easily snatch from iTS, break their uploading rules, and upload to what/waffles for easy upload buffer.
But you didn't hear that from me. =]
