Ib don't care about a scientific experiment
i will run a few racks,set up some shots and know
if it plays good for me is the only concern I have
my problem has always been hitting the ball accurately when I hit it hard
the long heavy cue improved my game considerably
now i want to see if it is the weight alone or length alone or both together
just an informal practical experiment for me alone to find what i like best
Black ball
your advice using lead tape is right,i forgot what i was doing
i will also try the weight at the rear of the cue and other places
thanks for reminding me
golfers always used lead tape easy fix
thank you again
