As a side note: What I feel is, that I'm "bumping" my hip to the left, and my knees just sorta follow along. The trick for me was to keep my spine angle in check, i.e. spine is the same at impact as at address, or pretty close. this gets your weight to the left for righty players. The problem I had was I swung to hard, losing my balance due to my shoulders being to level, and losing my spine angle, there fore I couldn't maintain my balance. Also Key #1 plays a big roll in this, as does Key #2.
I found that Slowing my swing, i.e. tempo also helped a bunch, and helped me finish my shots much better, all this was due to mvmac's guidance. I hope this helps some what.
I really appreciate it Greg. Your advice will help. Mike and Erik have helped me tremendously as well.
I will focus on my spine angle the next time out. Yes, slowing down has helped with some other issues (this video is at around 75%).
I will eventually get it. Even a bit more of a bump will be better than what I had last year. More weight on that left side at impact and a balanced finish has already helped my iron play. Any forward hip movement should help when I start work on keys 3, 4 and 5.
