I wasn't aware of the Aptitude enchantment, of course it's been a year or two since I made these builds too. We need to keep in mind that these were not intended to be optimized builds or used in tournaments. I made these for use in an actual game where things that were too powerful did get trimmed [<cough> druids <cough>].
And if you can get an unassociated level of barbarian in there without incurring xp penalties or losing and delaying feats, good luck.
