Very very interesting...
I got caught up with all different cue weight crap about two years ago. Everyone on the planet starting playing with light cues, seems to me that people were saying lighter the better.... 16oz, 17oz, only way to go.
So...
I went to a lighter cue 17.5 oz, and at first I was like this is great.... But over time i could tell something was missing, but i couldn't put my finger on it.... So i started logging long hours on my talbe, to mess around with the weight, adding, and adding, and adding until again it felt weird. Landed right at 19 oz, same spot i was playing with before, and now i'm hitting the ball better then ever.... Never again will i drink the kool-Aid.
Balance point is very important to me as well. 1-2 inches in front of the wrap and 19oz, buuuuuuuuuuuuuuuuutta! I havn't played this well in a couple years.
How a cue feels including the taper is most important. The rest in my opinion including weight and shaft (ld or maple) is Kool Aid. No substitute for time on the table hitting a million balls which breeds that elusive consistency we are all striving for.
