This wont answer your question, its just some personal wisdom(not that I have much of that). This is one of those "If I were in a simmilar situation" type things.

Say I was think of something that could be done to possible make the outcome of a situation better, since I've gone as far to think it up, I may as well go ahead and do it!

Unless, of course, your on a time constraint...

Nothing more to see here, move along
