Personally, I majored in Longswording in MHFU, but for Shen Gaoren I changed tactic to a lovely hammer. Reason? I was too stubborn to fight Rathalos and make Wyvernblade. Shen Gaoren is weaker to fire than Thunder. Well, technically, both Fire and Dragon.

Basically, you need to make a powerful Fire weapon. My hammer was one of the upgraded Gunhammers, but Rathalos' Wyvernblade line should be fine. :)
