Hitting the ball reasonably well - and pleasantly surprised with my few course outings - but cannot shed the dreaded trail arm chicken wing / lifting in backswing. I REALLY want to get the motion cold so I can move on to more interesting topics. I've gone back to the beginning more times than I can count. I've watched the "swing fix" videos several times. I've read comments from everyone here. It's all been helpful. I now think I have a pretty good understanding of where I'm failing but can't, for the life of me, break the habit.
I've narrowed things down to, what I believe to be, the main culprit: I'm I not turning my lead shoulder down enough, bringing the club back too low, and then overcompensating with the lift. I know - it's a feeling - and I just have to train myself. Plan on spending a good bit of time with Tom's "club too low" fix section in hopes if sorting it out: https://saguto.golf/courses/1118971/lectures/23973943
@Tom Saguto 's description of the well-intentioned attempt at getting the club around the body but swinging too low (about 1:30 into the vid) appears to be exactly what I'm doing wrong. I don't believe I have roll issues.
I'm posting this because I'd be interested to hear what swing thoughts have helped fellow Saguto golfers break the habit. When I stand over the ball I'm thinking about 3 things: 1. get that shoulder down; 2. hands in; 3. shoulders turn around body. That, of course, is too much and I'm generally only good for 2 out 3 on a given swing.
Based on my results, I don't think I'm TOO far from putting this together. I'm doing a lot correct with my swing: setup appears good, weight stays forward, arms straight throughout, some decent hip turn, etc. Here's a screen shot (slightly off-center) of a SW off the tee just before impact:

I look at that and I see a fairly good result but it took a steep (and unreliable) downswing to get there. Like all of you, I want consistency.
Any and all suggestions welcome!
Thanks for reading,
