AC Info

[DME543]

I have Tourney Armor which states it is +5 Heavy Armor and I have +4 Plate Mail for my level 8 Pally. When I interchange them my AC does not change. I have no other AC enhancements. Am I missing something? Let me know if you need more info.
Thanks

Tourney Armor (http://i153.photobucket.com/albums/s220/jgould2005/DDO/Items/TourneyArmor.jpg) is ac 7, +5 enchant, max dex 2, armor check -3. It's essentially +5 Mithral Halfplate (without the benefit to weight or ASF). It has lower armor value, but higher max dex making it the exact same "Total Armor Protection" as +5 FP. But, it does benefit from lower armor check penalty.
