Well, what is your Parry rating right now? I imagine it's low. That is how large the proc rate will increase (Note, it does NOT mean you will use Overpower that much more).
If you find your Rend wearing more than 6 seconds before you kill a target, you could go with that. If they DO last more than 6 seconds after, then check the damage.
This is the way to calculate Rend's damage per tic:
1) (Main Hand Weapon's Lowest Damage + Main Hand Weapon's Highest Damage) / 2
+
2) Attack Power / 14 * Main Hand Weapon's Attack Speed
+
3) Base Damage of Rend
Multiply that by two to see how the glyph will help.
On top of those two, I imagine Charge and Thunder Clap are possibilities, too. I don't know how much you use them, I only know that you have them at that level. Cleave looks good, if you are the type that fights multiple mobs at once. But you'll need to keep lining them up, as the glyph becomes useless the moment the +1 isn't functioning.
Tough decision. Sorry I couldn't be a lot of help (I haven't actually leveled a Warrior, I was just bored and did research).
