Those look beautiful J. The wings on Left were once on the on the right? Is that correct? The Skin is critical to a wing. Everything is important as I am sure you are aware. You are being to hard on yourself. A bbq to a fry is impossible to create. They will be different,again the skin takes on a different texture. For me,for what you are trying todo is like this.now attempting to master traditional buffalo sauce on the grill. first attempt wasn't bad, but definitely need to be more crispy. i think i need either more grilling time, temp, or both. may also attempt to grill, sauce, then toss back on the grill.

season the wings,whole wings only for me. I would only Cut them after cooking,before the sauce. BBQ the wings and eat a whole wing when you think they are done. The skin must break away as you bite through it. Not springy,or need to pull on it for a clean bite,nor can it be or mushy,soft. Just a little effort. Then I put them in a Huge bowl and toss,then serve asap. Anyway,hope this helps.
