I split then in half... chicken sticks to both sides... I'll dunk the meatier side in a little blue cheese and just clean off the other side as is.
Drummies rarely come off clean in one bite and i feel like I'm wasting good chicken if i don't gnaw at it a little to clean it off.
I also like the hot sauce/seasoning to chicken ratio of the flats...
Honestly im not that passionate about it and like a good wing either way... i think most people prefer the drummies so usually when i share wings with others, i have free range over the flats while the others are fighting over drummies. It's kinda like being the one guy that likes yellow starburst.
