General guideline/numbers for round brillants

[fullsun]

I would like to search for a stone that has good light performance (but doesn't necessarily have to be H&A) Would anyone be kind enough to post, or point me in the right direction where I can find a set/range of numbers (crown angle, pavilion angle, table%, depth%, etc.) that I should keep in mind when looking for a nice performing RB?

Many thanks!
