Good chicken wings? How not to buy fatty wings?

I am pretty sure not all chicken wings are created equal. I have had wings that were very fatty, some skinny, and in between. Is there a trick to avoid buying the fatty wings?

Also, how do you cook your wings? I just had some for lunch and they came out perfect. I tossed them with some spicy steak rub then grilled them over direct 400f on the BGE. They came out nice and crisp. Fortunately this batch was NOT fatty, just right.

Thanks
