Pve HoPF, or ram depending on what the mission/strike is. For instance I could see ram being useful in a situation like the abyss. Pvp Voidfang vestments with gift of the sun so you spawn with 2 grenades throw those then Rez with 2 more throwing everyone off when you come back and instantly have nades ready. Then usually a third by the time the second one is thrown. I could see the ram being useful too though.
