Weapon master advantage and modified weapons?

[faitfull]

okay, thanks for all the answers

did not try to provoke anyone, just hoped it covered. Will have a talk with my GM and let him see our discusion, så he can make a fair ruling.

however, shold anyone have more to say on the matter, I would love to hear it.

and if either Krum or Pullover have anything to add, please o please do!
