pvc tako not sure if you are around, but I extracted a LoRA from the PVC checkpoint you use. I used NAI as the base model for the LoRA (not sure if that was right - I'm new to this). Anyways, it seems to do alright with grapefruit juice & hll3.1. I tried it with a 20/80 PVC/grapefruit model merge, slightly modified your 2-shot prompt and it seems to yield okay results.
