I am a swinger according to GSED Alex Sloan and GSEM VJ Trolio and my own feeling. Do I have to have a conscious roll of the arms for a horizontal hinge? Is centrifugal force from the turning torso enough? If I use forearm roll I hit big hooks.

Welcome aboard, Mark, and thanks for posting!

The average golfer Steers the Club (3-F-7-A) and actually Reverse Rolls his Arms and Hands through Impact in an attempt to hold the Clubface Square to the Target Line. Therefore, he often needs to be taught the 'natural' rotation of the Arms. But at your expert level, such a conscious rotation will likely produce a Swivel Action (not a Hinge Action) and cause the Hooks you have experienced. In other words, you already are Rolling sufficiently, whether you Feel it or not.

As an example, Byron Nelson, felt he used no rotation of his Hands and Arms through Impact. Yet, when photos were taken in 1946 for his first book, Winning Golf, he was horrified to see not only the full Roll of Horizontal Hinging, but also a complete Finish Swivel! So what did he do? He simply refused to allow even one Follow-Through photo in the book! The Address and Backstroke are well documented, as is The Top and The Downstroke to Impact. But from there on there is nothing until his graceful pose at the Finish. That solved the problem for Byron, but it sure didn't help his Steering, Reverse Rolling readers!

Bottom Line: There is what you feel...and what you actually do! And what you are doing is obviously good enough.
