The apples on Baker’s Delight got eaten by animals (I think). At least, there isn’t anything on the branch now. The backup of Crunch-a-bunch produced 2 apples. I picked the one on the right, as there is a spot of damage on it (better to pick it, before it expands).
It also looks like mine have been having some problems with their leaves.
Yes and no (from my extensive sample size of 1 apple…). CAB has the same citrus/lemony taste that Goldrush has. You can see the family resemblance there. On the other hand, the brix is much lower. My apple was 13-14 brix. It isn’t as acid as GR can be though- this may be what they are referring to when they say “Improved version of Goldrush”). A GR at 13 brix would probably make your eyes water 
CAB also seems to be much earlier apple, as it seemed to be about ready when I picked it. I brought it, a Gala, and a Baldwin into work. Depending on people’s tastes, the Gala and the CAB were the winners. I liked the Baldwin (“Colby Baldwin” to be precise, as I have a couple Baldwin variants grafted next to each other), but it was still a bit acid and only 12 brix, while the Gala was still crunchy and 16 brix. I think CAB had the most interesting flavor of the 3.
Have you tried either yet? CAB may actually be ripe soon- Gurney’s says that it is a mid-September apple.
