None of the above. What you do get is crap optionless BitTorrent support, the Limestore and a Limewire that uses much more of your computers resources.

Stick with 4.12. It's by far the best version they ever made.

Phex has a filesize filter, so maybe try that out. You can have both installed at the same time no problem, but I wouldn't recommend running both at the same time.

Click the fox in my sig if you want to try it out. It's free.
