interesting, thanks to everyone, and keep firing away, when I started the topic, I would have answered A for me, and thought the majority would have said B, probably could have put a D and E - all of the above and none of the above. I looked at a few of my teams, I have a pretty equal smattering of all 3 types of SF;s, some of my best ones look more like c than a in all honesty, shows what I know.
My best advice to newcomers reading this as result of the input so far, is many of these coaches have had success, yet they widely vary in opinion, there are many ways to succeed at this, don't get to hung up on any one opinion or method to guide your actions.
