Helicopter Finish? a good way to maintain lag pressure?

I was hoping to get Lag’s and other’s feedback on the Helicopter or Chicken Wing finish. I’ve noticed a lot of strong golfers (Arnold Palmer, Jim Thorpe, and more recently Tommy Gainey) use this kind of finish with great results. I’m definately right side dominent and have often struggled fighting an under plan hook. Going to a helicopter finish, I’ve recently been able to go at the ball as hard as I like, and with this type of finish, am typically hitting a little fade, it has almost taken away my fear of going left.

I know this is supposedly a sin, and according to all the pop instructors, is something you would never teach, but would like to get the thoughts of some on this forum of this approach?
