+1 for opposite color neutral. When did people start calling it Bi-CN lol. I love cubers and their excessive acronyms.
anyway. So naturally I tend to think in terms of the method I'm most familiar with and here's my argument for "bi-cn" vs. full color neutral at least as far as Petrus goes.
In Petrus, if you can only solve with Yellow up at the end then you have 4 possible 2x2 blocks. If you can solve with both white and yellow as base you have all 8 possible 2x2 blocks.
If you aren't CN then for 2x2x3 you have 2 options because they must contain your base color. The only way to get that last 3rd possible expansion would be to go full CN, but that's entirely not worth it.
TLDR; Full CN in Petrus only gives you an additional choice for expanding to 2x2x3. Not worth it.
