Where are you looking to improve? Your a 1.8 handicap, so your swing is pretty much solid, and it looks pretty solid from the video you provided.
I could come here and say you should be playing a fade or a draw, or giving you suggestions, but your a 1.8, its kinda mute at this point. So, were do you want to improve. Do you want to eliminate a miss your having? Are you suddenly having poor contact? Do you want to play a different ball flight? Do you want to add distance?
Are you missing more putts than you should, missing more greens. Its tough to take a 1.8 handicap swing and say whats wrong with it. In that part of the game, golf is such a game of diminishing returns that you really got to be specific on what your working on, and what your looking for.
I'm a 6-7 handicap, and I can tell the difference between when a ball is struck high on the clubface or flush, The trajectory and feel is totally different. Right now I am struggling with being slighlty fat with the ball. I mean this might be the difference 1/2 and inch more forward the clubhead needs to be. That's how scary golf can be. I think Erik said once he was working on pro's who were hitting it a couple grooves to high on the clubface. What's the distance between a groove. Less than a 1/4 and inch. But to them that could mean a trajectory that is way to high, or coming up short of were they need to be.
