Welcome to The Sand Trap. Thanks for posting. A couple of admin things.
on the down-the-line angle, have the ball line upon your toe line. It helps us see your positions a bit better.
Film in slow motion and edit the videos to just the swing.
Give us a bit more detail on ball flight. You say slice, but does it start left then go right or start right and go further right?
That being said, there are some great full swing drills in the thread below. Start with Day 1 - 5. Film yourself doing the drills and post the video here. There are no short cuts to a better swing, but proper practice can get you there faster.
I almost always think of it as the kiss of death when I make an easy birdie on the first hole.
I've had some really odd rounds in the last few weeks: 42-33, 41-34, 40-35, 38-44, and 37-40. I'm not sure why it's happening. It may be because of the heat and exhaustion near the end of the round, but then some of the rounds have been reversed where the big number is on the front 9. I think for me, concentration is my biggest issue. It's hard to concentrate for 3-4 hours.
Well, today is my day off, time to work on the Harley. Tomorrow will be another day on the course.
If THERE is going to be an exception on the tee box, then you are contradicting yourself. Using a line on the ball to line it up is either legal or not. Placing an alignment stick down on the tee box is just as illegal as putting one on the putting green.
It offers just as much advantage on the tee box as it does the green. It assists a player in lining up a shot. I sense the conflict within you. Let go of your hate.
Added: For the record, I did read the article, and it reminded me why I don't read the mindless drivel in golf mags.
