Umm since today when i checked the enchant in my list of enchants, says right in the window there requires iLevel 35 item. Wowhead is not 100% current especially when it comes to things that have changed in the last year :P In fact if you read the comments on the enchant about the 5th one down starts a discussion about where to find the required iLvl 35 items.
Anway a good rule of thumb is check your spellbook before you rely on WoWhead.

the +29 enchant has no such restriction and would be usuable on the BoA items
