What you are prosing is called semantic differential. Think very carefully about the terms you use... it it not as simple as you might think. getting those terms right is the single hardest part of this technique and has the potential to radically skew your results. There is quite a bit of information out there now that you know what to call it.

It is really hard to get around that when people administer the survey and people are taking it.
