Full roll ("Wedding ring up") to get rid of Chicken Wing!
Full rolling the flat or arched left wrist will get your left elbow pointing downward, the opposite of a chicken wing. (left elbow rising)
Do it properly WITH the Twistaway and the pivot Brian describes in the video (flat shoulder turn, flat sharp turn of right hip) and you cannot flip OR slice!
It is great "training"...and possibly the start of a good draw swing/way to hit a draw.
(with those or some of those components)
Add "Flipper" (COFF Video) drills in for more "training"...
