I have looked into this some more.
Graves golf academy will try to train you into being a Moe Norman clone. It can take a fair time and may not suit everyone.
Kirk Junge used to work for Graves etc and developed a swing for impact position. It isn't that hard to master and worked O.K. for me.
He also has a version called the Minimalist Swing, which required even less change to an individuals swing. It is similar to the Channel Lock school , setting up with a closed shoulder line to target that promotes an in to out swing path.
Then I found Jim Venetos on YouTube. His school of thought is similar with a closed shoulder line to target and minimal body movement during the swing. It looks a bit suspect, but I am getting great contact and distance using it. I think my back is less sore using this method too.
For me the actual mechanics are less important than achieving reliable results and quickly.
xrman........all good,wish you well,mechanics will keep on keeping on imo,....knowing mechanics can assist in fault finding.....and lots of other goodies along the way,BUT......each to their own,keep it up....cheers
