i've always heard that running around 80% (like you mentioned) is the best scenario, but i'm sure being slightly off (~70%) is not a big deal whatsoever, that is if the price catches your eye. I'm assuming that price is a big issue for you though, since you are quoting 720's running 81%. Why not by these same injectors? Or better yet, run the modded 800's and use a bigger hairdryer.
