I don't think Craig has a stable BB b'c after he grew it the first time and got two different plants with two different fruits I don't think he grew it again, knowing it was unstable.
He said one plant had RL foliage and looked like Black from Tula and the other plant I think might have been PL and had fruits he described as being a bag of seeds.
But if it's still messed up one could just as soon get a PL with large fruits and an RL with weird seedy fruits.
I could be wrong but I've seen him post more than once about his experience with BB.
What he said he did stabilize was Taps, which has bugged me for years. Has to do with leaf form, tho, not the fruits.
