As far as I'm concerned, they go "hand-in-hand"....I couldn't have a pile of one or the other, it would have to be an even mix....
Sad thing is....I remember when "wings" were considered a "scrap cut" on the chicken and I could get them for prices like $.79 or $.89 per pound...NOW they are the "KING CUTS" with prices easily exceeding the "ONCE KING" breasts...I can get "boneless" breasts these days everywhere for under $2 per pound, sometimes much lower...
