OK, I'm up late trying to remove a virus from my laptop. While that progresses, I'm watching your video. I'll give you my 2 cents. Don't take anything the wrong way, of course, these are just my opinions and observations:
1. First rack you hit the 7 in the corner and bumped into the 5. Bad move that could have ended your run. Better to plan on coming off the foot rail between the 5 and 13 (using some right english), or just to bump the 13 a little for a shot on the 5.
2. The next shot (rail shot in the upper corner). You stood up just during or after your follow through. Watch your head in the video. No reason not to stay down on the shot and relaxed, especially when shooting a tester.
3. You looked a little lost on the last 5 or 6 in that first rack. (What I look like, too :smile
4. 14 ball break from behind the rack - I might've put some left english on that shot to bring the cue ball above the rack off the side rail.
5. Here's what I saw in that second rack. You had the 12 as a perfect break ball with the 6 to get you in a good position for the 12. However, you were on the wrong side of the 6 and from that distance you probably couldn't have held the cue ball. It's hard to tell, but maybe you could have. Or, you could have shot the 6 and followed the cue ball into the foot rail and back for the 12. In any case, you had the 1 to help you get on the other side of the 6. If you could have cheated the pocket on the 1 and come around to center table for the 6, you have been in a good spot for the 12. If you couldn't cheat it, then maybe a good draw back to center table would have worked. Having said that, you did manage to get on the 2. Was there only 1/2 a pocket to shoot at?
Overall, nice stroke. Just be sure to stay down and relaxed on the more difficult shots.
