I have the seeds of four blacks and want to grow to sell to a local chef. I want a good taster (obviously) which I assume all fit the bill, but I'm looking for production specifically in pounds per plant. The only one I've grown is JD's which is a great tomato and moderately productive but I wasnt' fond of the 'grazing' around the shoulders but not sure I can get away from that. I know that Cherokee Purple looks different while the other three kind of look the same to me (in pictures at least).

Paul Robeson
JD's C-Tex

I'm not at all opposed to growing more than one of these but wanted to make sure I'm maximizing my space. I've showed the chef pictures of each and he is fine with any. Thanks for your time.
