Joe>>>Loves his Sledgehammer
The Bunjee Jumper has never been beaten in heads up competition with
any other jump cue. This includes every single "name" brand cue you
can think of. There are several others that have similar performance
but none has performed all shots as well as the Bunjee.
BUT personal style and preference play a big part in how well a
particular cue "works" for you. Keep that in mind.

Prexactly.

Does it have to be this fat to be stiff enough? This must be the main
source of weight.

I don't know if there's a point of diminishing return with lighter and
lighter jump cues, but why not make the handle out of something much
lighter than maple, like balsa (or plastic tubing)? And why not make
the light handle longer and the heavy shaft shorter?

I think the optimal weight for a jump cue is 6 oz, the same as the
ball weight. This is when the energy transfer efficiency is best.
When there is a missmatch of masses (in either direction), the
energy transfer decreases.
The only reason I can think of for a lighter cue is to get the tip
out of the way of the ball. When a light stick hits a heavier ball,
the stick will rebound back, away from the collision. There are
probably some extreme jump shots in which this rebound is necessary
for the shot to succeed.

Does a stick heavier than 6 oz. transfer as much absolute energy to the
ball with a slower stroke? In other words, should we take more into
account than efficiency of energy transfer to determine what's optimum
for the purpose?
BTW, have you seen any jump cues as light as 6 oz.? The lightest I've
heard of is about 8 oz.

That's the only reason I imagine too.

Yes, I was assuming the same before-collision stick energy, not the
same stick speed. I also agree that most jump cues are a little
heavier than 6oz. However, the shaft alone is a little less than
6oz, and back when it was legal to do so, many people jumped balls
very well with just their shafts.

Ron,
You mentioned equal weight for best efficiency. Would that be for a level
cue? For a jump to work is there compression which would need to be added to
the six ounce ball weight? Would that extra if it is so be added by the
stroke? What weight would be optimal for say just dropping the cue in a
controlled manner a distance of 6 inches?
Thanks,
Tracy
So would I. I bet it has a lot of the characteristics of the Bunjee. There
are a lot of good ones out there right now. (and a lot of them use Bunjee
Tips as well)

My sledgehammer weighs 9.2 oz. and another one that I have is 8.45 oz.
I don't think I've ever seen one in the 6 oz. range. Maybe Ron needs
to get off his butt and start creating these ulitmate weapons based on
the Professor Irwin Corey formulas instead of just throwing the facts
out all the time. Maybe he really will come up with a better product
and get filthy rich.

Lighter is better for the pure jump but you lose accuracy and cueball
control massively. I found the best balance to be about 8-9oz with a
practically zero compression tip. After that the shaft taper, tip size and
balance play a part. Contrary to popular misconception it is not ALL in the
tip. This was proven at the Sledgehammer booth at the APA nationals by Mike
Gulayassy and myself.

6 ounces is too light. You use the term "Optimal" the lighter the cue
the closer you may be able to jump, but you have a harder time getting
the cue ball out there with such a light cue. Since most shots will be
not 2 inches but a foot or more, Optimal would be a heavier cue. 8
ounces is I would say the best all around weight. Just out of
curiosity, how many times has anyone actually seen someone jump a ball
from 1 or 2 inches in competition? It may happen but the percent of
jump shots you would choose to do it are so small as to not want to
trade off the longer shots.

I agree with your points. By "optimal" I meant simply the ability
to get the cue ball to jump with the least amount of stick energy.
Other things, such as aiming accuracy play a role too. For jump
shots that involve relatively little cue ball height, and longer
distances, I use a full length cue instead of a jump cue because of
the increased accuracy (which probably comes from both the increased
weight and the longer length).

Why not simply carry around a whole golf bag of cues for different
length jump shots? At least 3 would be good for a start, 6 oz for
close, 8 for medium and 10 for long... At least the cue makers and
case makers would gettin woodies over the thought... Then of course, we
have the break cue and the regular cue, both with a couple of shafts in
case a tip blows up....
