Anyway enough fun... Yes AGS's type of Ideal cut or one that its software gives good marks to is a fairly safe bet. But it is not the only one and to lose sight of that the consumers will lose a lot. I love well cut RB's and they have a place on the market but lets leave room for other designs...

CBI fire | PriceScope

There are multiple SMTB threads with photos and videos that you can find by searching my user name. As to why CBIs exhibit consistent fire/dispersion with minute differences in crown angle and table percentages, I am sure @John Pollard would have a technical and thorough answer for that question.
