For me, in the last group it is "G". It looks like two different flowers in one. I do like both the others, but I am not sure about them. "C" has alot of veining in the standards which may or may not detract from it. I do think it has a place and should be considered for introduction (but of the three, this would be my least favorite). I VERY much like the "crisp" white standards on "E". There are many cultivars that sort of look like this which may cause Keith to not introduce this one. However, I think the edges of the standards stand out more than anything I have seen out there. I would introduce "E" & "G" and use "C" to try and breed a better flower.
