trigger upgrade (inferno)

[Artwood]

thats right, im upgrading my good old inferno, all standard, side feed, however, i may be getting a Inferno Double Trigger Grip Frame Complete from fat bobs, but i wanted to know how these would be fitted and how easy would it be? and also what kind of effect would i get by upgrading it. It would be great if someone out their knows something.
cheers.

With the double trigger you will be able to walk the trigger;)

i assum that means firing faster? but with two fingers?
