Tutor wanted to ask a few q's: offering BTC payment

So if I wanted to use mode 120, sha1($salt . $pass) because I have that kind of hashed digest, I would actually flip it around to 110 sha1($pass . $salt) and have lines that look like this:

8573db2460575106df5d4e0c7502c23f623a3174:pwd
8573db2460575106df5d4e0c7502c23f623a3174:another
8573db2460575106df5d4e0c7502c23f623a3174:foo
8573db2460575106df5d4e0c7502c23f623a3174:bar

and use the mask ?b?b?b?b (for 4 bytes of salt) on the command line? Is that attack mode 3 or a hybrid?
