This is fun, cracked a lot of secret servers today.
And I think the best cracker to use now is between v2.5 and v3.0. Most secret servers fall on that protection level.
For cracking private servers, keep v10.x, v50.x, and v100.x
@Witcher: You can still use your old approach. Select Password Breaker from the File Section and select Run so all your breakers will run. Then when cracking a server you can choose what breaker to use. In our case we can use a single breaker and run it multiple times.
