So what are the major advantages to having a .36" rear aperture vs. a .40" or even .52"? How about the same question for the front sight post (.52 - .72)?
Thanks in advance for helping out a newbie

The wider the rear aperature, the faster the sight aquisition. The smaller the rear aperature, the more "precise" you can aim it (at the expense of speed).
The Narrower the front sight post, the more "precise" you can aim. Remember, your focus when you fire is on the front site tip!!! The rear aperature is just a round blur.
That being said, if you can "center" the smaller front site tip quickly, in the larger rear aperature, You're above the military curve.
It's all about aquisition speed vs precision.
Standard disclaimers apply.... my .02, just an opinion etc...
