I have used every single bt client. I have did all the port fowarding, followed all the guides. I have verizon dsl 3mb up/78k up n i hav to say bitspirit iz the best program out dere. Even on the torrents with a bad ratio i was getting descent speeds. i avg a minium of 110 kbs. I am telling you guys azureus is good. But Bitspirit is better. BTW i use port 49152.
