Stormchaser, thanks for your response. Eye thought about that, but my first reaction to that is: NoFlippinWay! 
I really do not wanna do that, but yeah, I may have to, as a last resort. 
I'm not willing to go straight to that as an answer, not just yet. 

So, back to your suggestion,  would you use area render, just eyeballing the strips, then? Or, is there a precise way to slice up the render real estate that I don't know about?.
