I'd recommend more ath over more str/ps. If you weren't naked, I'd say go for it and have fun. However, since you want to play naked, speed is helpful even if you're only hindered by your weapon. I'd tone the str down just a bit to get more ath.
Something like 27/15 or 30/12. No need for a lot of ath when you're naked.
Good luck getting to 33 though. Insane grind.
