I prefer to trade via download links as this is quick & reiable. I have no objection to snail mail if that's your preference.
In a trade I will try to adher in full to your requests eg no writing on discs, DAO of whatever you need. I have no particular requests, I'm in this for the love of the live performance & always hope to get the best quality possible.
If I need something & you have it in poor quality I still may consider a trade as I'm happy to add to my collection & wait for better to come along later.
Let's talk, talking solves & resolves a lot of things.
