My swing video, have a look see

http://www.swingacademy.com/swingana...l.aspx?id=1712

Ball went straight, with a good launch. Swing speed was upper 90s. Looking for power leaks. My usual misses are hooks and pulls. But I'm usually on the fairway most of the time.

I look very flat at the top, and my spine angle straightens after impact. Are these issues I should fix?

thanks for the input...

What I see...
You're taking the club outside the ball on takeaway and you need a little more body turn on your backswing because it seems that your club head is pointed left of your intended target at the top. Also, when you finish it looks like the club head is closed. That might explain your hooks and pulls.
Try and hold your hips in the swing a little longer so your release occurs just before impact and you might see an increase in power and distance.

You are taking the club outside and it looks to me because of extending from the left shoulder joint. At address your shoulders should be relaxed and the joint should be to the side of the torso, not extended out, then it should stay that way throughout the swing. Why? The lead arm defines your radius which is best kept consistent IMO, and the joint to the side provides leverage in the shoulder, without which arm muscle is required on the down to keep it up with the torso. The best way to feel is to "glue", not squeeze, the armpit at address and keep that feel throughout. But that is not your only issue, and you noted it, sort of, in your post.

Your spine angle is actually amiss prior to impact. Do some stops at impact and compare your spine angle there and at address. Note how your hips are much closer to the ball than at address and since you do a good job of keeping your head from rising, it forces your spine to arch, and can contribute to blocks and pulls. I suspect the root of this is you are setting up a bit favoring the heels. I prefer equal distribution between the balls and heels of the feet, but if you err, favor the balls of the feet, not the heels. You also may be just a tad close to the ball. Another setup help would be to roll the hips under the spine more (tuck the tush). This will help straighten the spine at address better and engage the quads to provide better stability during the swing. Hopw this helps.

Thanks for the help. It's funny. Everything you guys mentioned is what my instructor mentioned. But I haven't seen him for a few months, so these issues have crept back into my swing since I last saw him. I'll try to post a video later on after I've practiced incorporating these fundamentals.

I feel you can gain an easy 15 yards in your swing.

It appears you are swinging mostly with your arms rather than the bigger muscles of you shoulder and especially your hips.

Practice
1) back swing with a full turn of your shoulder and hips, turn your shoulders so they are 90 degree or facing the target, the hips should be turned so that the right pocket is facing away from the target.
2) slightly dip your right shoulders
3) keep your right elbow closer to your body than your left elbow at your set up
4) generate more club head speed with the proper light grip pressure. Your grip pressure shoulde be as though you are holding a tube of tooth paste with the cap open and you don't want any of the tooth paste to come out.
5) start your backswing slowly until you have completed your full backswing and start your downswing with your hips and generate speed with your left shoulder turning left and switching with the right shoulder under your chin while keeping your head behind the ball.

Good stuff bro. I see lots of good things but here are the bad things:

tempo- slow down a bit especially at the top.
tug- don't tug the club down from the top. let your powerful lower body start the move.

Thats about it! A good drill for you maybe hitting some balls with just your right hand. It will improve your tempo a ton and probably keep you from pulling at the top.

Start the downswing with the butt end of the shaft, not the clubhead. Thinking about the butt end of the shaft will help you get in the slot better too and not come over the top or get 'stuck'.
