I imagine Cliff said to weave them to make them stronger against the wind possibly breaking off the grafts. You could stake and tie them as an alternative. The trunk looks like a good size, so I’m guessing you bark grafted the scions. Personally, I’d wait until the stump heals up in due time and then cut all but the dominant shoot. I had the same issues with leaf curling. It could be insects, over/under watering, or over/under fertilization. Here is a thread that talks some about it: What causes Persimmon leaf curl? - #9 by Jose-Albacete.
P.S. thank you for the Barbara Blush and Zima Khurma scions in the past. I have a few trees grafted from your scions. They are doing well, but I’m still waiting for fruit. I’m jealous of the quick growth you all get.
