Ok Thun and Yosh, here's a Trad Monk (Motherless Tiefling very good fit here) build with Pummeling Charge, Bully, and Pounce (so good with Monk because your enhanced speed increases Charge/Pounce range and straight Monks get Pounce nice and early at level nine):

Check out that unequipped, unbuffed speed! +16 Will is very good, but you really miss all the good ki-powers. Abundant Step can be nice strategically, but when you can Pounce 90 feet who needs it?
Base Monk:

Five less Will (six at lvl 20 I'd imagine) is a significant ding. Ki Power : Restoration is just such a nice convenience/slot saver, and of course all the quasi spells are very solid and fill gaps/add flexibility (Barkskin, True Strike, Spit Venom, Shout). Spit Venom for things like Big Bokken that are hard to hit otherwise, Shout for groups of foes w/ low Fortitude (like Ghosts and Hunt). Can also pick up the free Spell Resistance and Quivering Palm late.
So if you just want to Pounce around alot and assassinate casters and archers the Trad is good (can still escape as necessary with Abundant Step), while if you want something more flexible at the cost of godly Will saves go base Monk.
