I grew the F1 in 2017 (that F1 plant is known as MKX_A), in a shady location by a current bush. It had red, plum-shaped fruit, thicker in the middle than the two ends. They were very sweet, just like Medovaya Kaplya, but perhaps slightly more complex. The F1 was regular leaf.
I'm growing the F2, this year. I selected for a potato leaf plant, today, when I cut off the extra plants with scissors. The PL one wasn't the largest, though, but it looks like it could do well.
Here's my plant, so far, this year:
