Torrent spy is full of idiots who talk shite....
It probably is the best resource for torrents but you don't get straight answers on quality of the download whch is what i look for....
There are a few very good torrent sites out there with people who do report download quality and problems etc etc You've just got to find them
Torrentbytes is probably one of them but it's invite only and i haven't got any invites left
On the client front i use Utorrent. Simple, quick, fast and only runs at 3,000k in your task manager window so doesn't suck memory.
