Excellent idea (and a good way to address the point I brought up about overly rectangular florets). I think C vs D is pretty clear cut as in C the florets don't just look like rectangles--they are rectangles. A vs B is a bit tougher, and I'd say A is still nice because those don't look too rectangular at this distance, but B is definitely better.
As far as the angle of the cut, in both B and D, the florets don't lead your eye straight across as they do in A and C. This is outside the way in which the florets themselves are shaped, but still a factor.
Too bad we don't have an example of rectangular florets cut at a diagonal.
