Monk 2/Ardent 8/Slayer 10 with Tashalatora (Slayer) would have BAB +17, 9th level powers known, and 12th level monk abilities (including greater flurry). Psionicists can buff the crap out of themselves, and also can benefit from VoP without suffering too much (make sure to buy all the +5 Tomes you want before taking it).
