It don't mean a thing if it ain't got that ping.
The fact that you can deflect the cue ball more when you want to is a powerful tool if you know how to use is. Sure, it's another variable, but one that can be mastered to great effect. I can cut much thinner with a regular shaft as I can deflect the cue ball off line and bring it back with applied spin. It's kind of a half masse shot, but it's not nearly as easy to do with an LD. I won't say that you can generate more spin with a regular shaft, but you sure can easily get some action that's very difficult with an LD. Not all LD are created equal either. Some are whippy, some stiff. I think this is a personal preference, but I really don't like the whippy ones.I read/watch because they've actually done the tests. Unlike you who just keep spouting decades-old pool fables. You're the one that either doesn't understand or is too stubborn to face facts. Oh btw, the word is 'lose' not 'loose'. You probably won't believe that either.
Under normal play it shouldn't be much of an issue, but when you need that one "trick shot" your opponent left you to finish a rack it can mean the world. Fables or not, in the right hands a high deflection shaft is one other option available to run out. If the deflection isn't there to play with you just lost one option in your toolbox.
