Thank you Todd. That is exactly what I was referring to. Earlier you mentioned where you have situations when individuals whip out an 8x40 set of binoculars and try to compare them to a set of true compacts. I have run into similar situations where folks will whip out a set of 8x21 "X" brand that they bought at Walmart for $20 and then try to say they work just as well under all conditions as even a $90 roof prism compact or a $50 porro prism design of roughly equivalent specs.

Along that line of thought, the more I think of it I believe the Brunton's to be a porro prism design based on the shape of the binocular and the brightness level in comparison to some of the roof prism compacts I have/do own.

I, for one, would love to see you do some more, when time and money allows, with a different category of binocs as well.
