Interestingly, the cleft grafting in the end, when the plant is mature, still looks mostly like the splice one, the V parts of the rootstock don't grow anymore after grafting, and the tip of the V from the scion enlarges so much that it becomes as thick as the stem.

The best for now is doing the Xi'an Green, even though the Black Dragon was the first one and had a big advantage at some point, not sure why. Also the only one on tomato, even though 6 weeks later then the rest, is growing the fastest, also the leaves are visibly larger. Depending on how it does going forward, it seems like the better choice compared to torvum, even though it's just an old stable variety. Also, as expected, the tomato base it becoming much thicker, especially at the union, while torvum matches exactly the scion.
The lone pepper is doing ok, hard to say yet if there is any clear advantage.
