just sneak a vigilance on the pally.. /grin
In all seriousness don't.. that's a joke.
Check out the flow chart posted here. I think it was posted already... but it's so easy to understand that every new warrior tank should see it.
Vigilance your highest DPS.
Spam heroic strike till your fingers bleed.
Remember the goal of threat production is to stay above your dps. There's no worry if your at 5k and your dps is at 3k... even if your paladin friend is at 10k, all that extra threat is only good for stroking epeen.
When I'm tanking a boss my goal is to produce enough threat to keep a buffer zone of ~10% over my DPS.. ie: considering my threat as 100% I want my DPS at 90%... that provides a minimum of 20% cushion before they pull aggro (melee) or 40% (ranged). Once I reach that TPS level, the rest of my itemization goes to survival. There's no reason for me to be double my DPS' threat; if im double my DPS' threat then I can afford to wear more mitigation.
The only goal of threat production is to stay over your DPS.
Hell I can out TPS my palladin co-tank... if I sacrifice 10% avoidance and 5k health. But whats the point IF my DPS never pulls aggro?
