I can't remember exactly who it was, but I do remember reading on here at one point that someone suggested using your 3rd best RP as a closer, so that your top to options come in when you need them most and that you also have someone solid available to shut the door when necessary. Once I read that, I started using it and have gotten decidedly better results than I had previously. So, FWIW, if you really want to use a closer that's the way I'd suggest you do it.
