The only way to really find out is to have a huge selection of frames and start offering them up along side each other for curve and size etc.
I can say for example - the Correspondent will have the right curve but can’t say for certain that the size is large enough from memory without comparing them.
Hmmm, I think you could get pretty far by comparing BC's of different models in a store. You can easily see when they are the same, making reflections appear the same size. And I suppose there are not too many BC's available since that would only be a cost for Oakley.
Of the 10 Oakleys I've got, all except one share the same two BC's. The last one (EVZero Path) is not spherical though, which I suppose is the case with any "mono" lens.
