Armour tallies are out of the question at the moment- I don't have a high level scavenging alt to farm for armour shards nor do I have 9500 gold to buy one armour tally (I know they're not that much, but the only one I see on the AH atm is listed at 9500g by some nub, lul). I will save armour tallies for when I get my conqueror set.
I was at first thinking to slot each piece purely with toughness. But then, I'm getting a little bored with my BG doing almost no damage - all my purpose seems to be is soak up damage and let others have the fun of actually killing the enemy. I know this is kinda the point of a tank, but meh, it doesn't really feel very satisfying to be doing close to zero damage. I'm used to playing DPS classes, this is actually the first tank that I've leveled to almost R40. I used to play a WL on retail (shock!!) and I'm used to wtfpwning people in 3 seconds. Back on retail, believe it or not WLs were even more overpowered than now, and there was this ability (I think leonine frenzy?) that let me, as a R31 WL fresh into T4, solo some R40 players. So yeah.

So, I was thinking, perhaps I could slot only half of my gear with toughness tallies, and the other half with strength?
Here are my stats at the moment for some context:
R37/RR49
Strength: 203
Weapon Skill: 242
Initiative: 221
Toughness: 602
Wounds: 737
Renown points are all stacked into block/dodge/disrupt.
Tactics are: Rugged, Terrifying Foe, Anger Drives Me
Mastery points into Loathing until ADM, then malice.
