I personally used Rathalos Soul armour and a Longsword for all of the necessary Quests, gemmed for Reckless Abandon +1 and Attack Up (Large), iirc. In my opinion, that is sufficient to get you to at least HR7, maybe further. If this becomes too weak then get Tigrex S armour and gem it as you wish (I recommend Autotracker).

I haven't played MHFU for a while and I'm on G*** Quests, so this is as much as I can remember. Hope it helps, and good luck!
