How should this dwarf take the throne room?

So I'm pretty confident with stealth-ing the throne room, but not with melee. I'd feel a lot steadier with more healing but I'm not sure that the turn count isn't going to creep up too quick for me to collect much in extra consumables. Do I just try drinking quickness wacking Morgoth, cracking a sil & running? Grabbing song of slaying? (I have no rage herbs). I'm thinking I'll wear the galvorn armour but annoyingly it leaves me at 29.5lbs, where Nevrast cracks 75lbs of heavy armour. Lighter seems better for riposte & I need the str rings just to be carrying Nevrast...
