brute force tools

[<don.williams () verizonwireless com>]

Frequently I attempt to brute force web applications and have found a few problems with the programs I have used. For 
instance Brutus always informs me a few successful attempts yet when I try they fail. (2) Webcrack not reliable. 

What I would like is some other tools you may have used with good success and hopefully a perl based script which 
enumerate common words substituting letters for numbers as users do everyday (ie. pa$$w0rd). Also attempting the crack 
ColdFusion it only requests the password not the user name / password combo as most tools only allow. Windows or Linux 
is fine.

Thx
