Your build looks ok. I'd want the cleaves for damage against multiple targets, which there usually is going to be, but that's just me. I'm sure you've made your decision, but if no cleaves I'd at least want Precision over PA, always ways to make up 5 pts of dmg. I definitely lose OTWF. I played an Int to dmg melee arty for a while, starting 15 str, with +5 tomes, and a 6-10 item at cap and epic levels, plus rage and heroism pots and I never had a hard time hitting anything except once in a while EE 29-30 content. So I am sure you're not going to have a problem at all.
