Daggertooth's Belt: Build help

[Snike]

Ok, so I have had this belt in the bank for a couple months. I've just now started looking to make a build to utilize it. What I have figured so far that I want to get out of it is this...

Need to be high AC build other wise no reason to use it
Using it on a fighter to only save 6AP doesn't seem to be worth-wild to loosing a belt slot
A pure build would be nice in anticipation for level cap increase

With those things in mind I have been looking towards ranger or paladin. Paldin was my first choice but the stat spread on the class just seems too difficult at getting a high enough dex required to getting the best possible benefit from the belt, was thinking dwarf pally needing 26 dex for the +8 dex bonus on a mith BP. A human pally would be a consideration because the 20 dex could be much more easily achieved for a +5 dex bonus and an extra feat, but it would also take away from the purpose of the belt in max/min of AC.

So today I have just starting considering Dwarf Ranger but again I'd be pushing the stats with a needed dex of 30 utilize a +10 dex bonus on mith breastplate.

How well can a sword/board ranger tank?
Any thoughts or ideas concerning this belt? I thought it was a great item but I'm finding it hard to get the belt into a build to gain the best possible outcome.

Incase someone doesn't know what it does:
Daggertooth Belt - Belt, +3 Con, Enhancement: Fighter's Armor Mastery 2(adding +2 to dex bonus of armor)
