There is more demand for the heavy wood grain version. Personally it's kind of frustrating people keep jumping on the heavy arrow wagon. there is a limit. The AD black is actually pretty heavy gpi. For whitetails a 575-600 grain arrow is plenty!!! I'm really not sure what kind of zombies we need heavier arrows for. That black AD shaft give great arrow weight and awesome performance. I'm not an elk hunter (only because of pocketbook) but I've blown through deer from every angle with arrows under 600 gr. I don't like the weight of the woodgrain AD. Just dogs down my whole set-up. Can't hit anything. i remember when bullet mfgs were really pushing heavier weight bullets for standard deer calibers and harder jackets, more penetration, less expansion. I thought it odd because I was already shoot through deer. Now as bullets are better, solid copper and such like barnes. They make more loads are for lighter weight bullets.
The woodgrain ones are so easily available, I'm tempted to try the woodgrain lites just to see if they work. My draw is pretty long. My bow is 51lb @29 drawn to 31". Probably too weak.
Sorry, not sure where that rant came from!
