I posted a video on youtube a couple years ago about aiming GB/QB. I gave a method to see the imaginary ball or ball division with actual lines. I called it, Eclipse Aiming.
Using EA, I can sit "ball A" on the table to use for a pocket, then place an OB any where on the table and try potting full ball onto "ball A". I can come extremely close to full ball hits most of the time.
Something happen to my Youtube account and the video is gone, so I might make another and post it on AZTV. It isn't smoke and mirrors or an 'is-all, end-all' for aiming. If you are questioning a pot, you can use it to confirm your aim. It will be the closest thing to potting like a pro snooker player by using an aiming system. Best of all, it only takes about 30 seconds to learn!
Down side to the method:
- shots longer than cue can be tough
- getting lazy and not focusing on the actual line and OB coverage.
Anyone interested?
