Stars $3-R WSOP Supersat: Right time to go all-in?

[GrunchCan]

The limpers are both bad players. They are both loose limpers, weak and passive. I am confident that my PF raise wiill either force them out, or they will call with much the worse of it.

The BB I'm not too sure about. I haven't seen him make a raise like this before.
