i did not want to derail the other elbow drop thead so i started this one
a common "tip" is to keep the cue level
in order to do that you have to drop your elbow AFTER CONTACT
why is that bad????
just askin
Yes, to keep the cue level, you have to drop your elbow. I wouldn't call it 'bad'. It's much more complicated of a stroke that it has to be. It allows for many opportunities for errors to get in the way.
The only time it's important that the cue is level is at contact with the cue ball. As Tony said, a pendulum stroke will allow for a level cue at contact, and the tip will dip during the follow through. That is a good thing.
