I've got the back story and the barbarian bit can easily be cut out as it really doesn't affect much. Just didn't find it relevant since I was strictly talking build here. Oh well perhaps it is a tad silly I suppose, or at least not practical since I was wanting to stick to monk mostly. Would've liked to do (un)monk/(un)barbarian that only took one level of monk. However the trait to get around that alignment restriction would require me to be an aasimar and they are frowned upon at our table.
As a side note I don't see how people don't think a one level dip in unchained monk is the absolute best dip for a pure martial. Use a seven branched sword, or whatever monk weapon suits you as there's tons now, and get an extra attack at full bab when you full attack for a one level dip plus some monk crap and a decent selection of bonus feats? Sold.
Well flurry of blows does not work while wearing armor or using a shield or carrying a medium or heavy load. The same with the AC bonus.
That might limit your choice of builds considerably.
