The guys in the bottom row keep the club, arms, and hands more in the so called FRONT of the body on the Backswing, and also try to do this on the Downswing. They are probably using 10-6-D..."undoubtedly the most widely used Basic Plane Angle"... Turning Shoulder. Look at 10-6-D #2.
Do you think they are using the A or B versions?
Howell may actually use a variation of the 10-7-E.

The guys on the Top row appear to be more on a 10-6-E Hands Plane. They get the arms, club and hands deeper BEHIND them on the backswing. After the Backstroke 9-2-5#2 stage is reached, They then go into one of the Shifts 10-7-O.
