Shadowknight/cleric duo gear question

[Roth]

I rolled a troll sk and I got a great weapon, a few decent armor pieces with high ac, and the rest banded. I'm wondering where I go from here... if I'm primarily going to be duoing(I'll be virtually the only dps), how efficient is each stat for kills/per hour? I can see why ac is the best for a 6 man or a raid. If you have other people helping you dps, there's no point focusing on dps at all. My problem is when I'm going to be the only dps, I'm having a hard time knowing which stats to go for. Dex, Str, Ac... how valuable are these in comparison to each other for duoing with a cleric?
