Best loadouts for BTB

So what’s the best loadout for BTB games in your opinion? Well it’s very likely that in contains at least plasma pistol and plasma grenades, so what about armor ability or tactical and support upgrades? I use two different loadouts for this game type but the main loadout would be Covenant carbine, plasmas, Jetpack, Wheelman upgrade and Survivor upgrade. I just chose Pathfinder as the next specialization so I could switch the Survivor to Gunner upgrade but I think this was big mistake because now I think that Survivor works better with the Wheelman upgrade and jetpack whereas Gunner upgrade doesn’t support other features much. Little pity that I made too quick decision for that!
