This is basically the same as asking which ABer is best, which is against the rules. Please read everything found here: http://www.neofriends.net/phpBB2/viewtopic.php?t=1290
Sorry buddy but its against the rules to ask, to avoid spamming from new members. Please read the RULES.
\ Yes, you do, but don't spam, they'll take the points away, and you can only get 40 points max/day anyways.
I'm sure that you'll figure out whats suitable for you by just reading around what other people have posted about the various ABers avaliable. In the end it's all down to personal choice anyway. That, and how many points you manage to save up
