Thank you Harald, and John, yes that shoulder packing is what I'm working on lately... on the downswing my shoulder tends to come up and forward, noticeable in this video from 3 weeks ago https://youtu.be/h1G-W5SIvpw. I have the shoulder pack pretty well on the start, hike, upswing, and top of the swing, but for some reason that downswing I lose it. Slightly better in last few weeks but it's going to take a while to master it. I did notice just this week that if I keep the palm facing back (instead of rotating the thumb to point towards the back) or even keep the thumb slightly forward, the shoulder has less tendency to come up and forward. If anyone has any tips for this issue I'd love to hear them.
I am getting closer to swinging that 32kg, yes! Sinister is definitley a goal, in good time...
