I don't have a tonne of experience, but I use Makeup as one of a couple of compensating factors when I have two guys that are similar enough in ratings to go wtih either. Things like makeup, temper, etc, depending on your practice of moving guys through your system, in my opinion can make a difference.
Guys like Tec or MikeT can give you a more accurate response, and also some real HBD world examples that you can use to help you make a judgement.
