If it's that much of an issue why not have both? On most bosses, especially in BT I use both, kinda neccessary on one like Bloodboil where your armour gets a serious panning, especially if you get a refresh.
Commendation for Stam & oh sh!t avoidance, with watch and stoneshield pots for controlled mitigation.
Usually I have the furies deck with the commendation for a threat/stam combo, with option on blocker. Romulos vial never dropped, or RL's had a brainfart on the roll, Shard roll is always lost, but after seeing the tanking trinket that Bloodboil dropped, hoovered up by the other warrior on DKP then I'd be tempted to use the commendation and that, if I could get grubby mitts on one.
