I have lost the proper PP#4 feel lately......trying the glove under the left armpit doesn't seem to work for me.......then read some of the archives at Lynn Blake forum.....seems that I was simply pressing my left arm against my chest.....WITHOUT pivoting my upper body and hips.........the proper feeling of tightness at the left armpit is PIVOT BASED....I was losing the connection of the left arm to the pivot.......lose the connection ....lose the swing.
