The advice I can give you is to not download more than one file from each host at a time. Especially if it's video, but also audio. And especially if they are rare files.

1. You get the file faster Downloading two will give you half the speed in most cases.

2. Host may go offline and you have several bits of files.

3. He may kill your upload for being greedy.

I have mine set on two, so if anyone tries for 3 files he is banned
