WotLK Cloak enchant for melees: 400 AP vs agility

[zorino]

For pvp, some say that Swordguard Embroidery (400 ap - tailoring) is better than +22 agility and others say that it is better agility.
What do you think?

[Shred]

Have you taken into account that using the tailoring enchantment requires tailoring? This is, you have to compare it not only to the +22 agi enchantment but to the entire profession you are losing.

On the other hand, tailoring has nets, which are grossly underused.
