Before even beginning the testing of the ball I performed a bounce test to
compare the bounce of the DHS 3 star plastic ball to the Butterfly 3 Star
Celluloid ball. The plastic ball has a lower bounce peak and is less
responsive on the table surface, this is because of the slightly larger size
of the new ball and also it's plastic material composition.
2. The Shape/Roundness
I also did a spin test with both balls. With the prototype plastic balls
there were a lot of issues with how spherical the balls were. This is an
issue which seems to have been almost overcome and the plastic balls I
tested were of a reasonable roundness without too much inconsistency from
each other.
3. Durability
I did a number of tests with the DHS 3 Star plastic balls and none of the
balls have dented or broken during that time. I played for 3 hours to
complete my review and still have all of the balls I used during the testing
, all intact. While there have been a lot of rumours that these balls break
easily, the ones I used seemed to be fairly durable.
4. Topspin Counterdriving
In a close table counterdriving situation the bounce of the ball does not
have an overly big impact on play. While you remain close to the table the
bounce is easy to adjust to. The main differences are that the plastic ball
feels slower and heavier and you can almost feel the marginal size
difference while you are playing. At this range from the table and
considering the simplicity of the technique, there are not many changes you
need to make in this area of the game.
5. Topspin Looping
When I started to loop I definitely noticed that I was not getting as much
spin on the ball and it felt strange at first. I had to transfer more weight
into the ball to achieve high spin and to be able to execute shots with
more power. This was particularly obvious further back from the table where
I struggled to adapt. Also with the lower and slower bounce the ball fell
shorter than a celluloid ball would and I often found myself picking up the
ball late in the bounce. This meant I had to create a higher arc on the ball
and force a higher trajectory. The alternative to that is to move closer,
which is what I did. At times it felt more effective to drive through the
ball more and I found that strokes where I hit a little flatter instead of
trying to brush the ball were more consistent.
6. Creating Power
A common misconception about the new plastic balls is that they are
incredibly slow and you can't produce much spin. This has been
overexaggerated, the actual results are marginal and the plastic ball is
quite close to the composition and capabilities of the celluloid ball. While
it can be hard to hit through somebody who is blocking, you are still able
to produce powerful strokes. They don't quite have the speed of the
celluloid ball but they can still be very effective.
7. Short/Long Pushing
Pushing proved to be more difficult to control than topspin. The ball
bounced higher off the rubber and also higher on the table. It took a little
while to try and reduce the height of our pushing strokes, particularly the
short push. I found that I had to give the ball an extra little push in
order to generate the spin I needed to keep the ball low to the net. The
short push is now harder to play as the touchy stroke that it is with a
celluloid ball. You need to take the ball a little earlier and create more
angle and variation to produce a tight ball. You need to be able to play
with a bit more force and confidence in these exchanges as the ball can
bounce higher when playing underspin.
8. Service
While it is not possible to match the celluloid ball for producing spin on
service, it is still possible to maintain good quality service with good
spin. Again, when serving sometimes the ball bounced a little higher, but
after the initial bounce on the table it slowed down (as noted in the bounce
test) and it sometimes became possible to serve comfortable short serves
with 3 or more bounces which would probably only bounce 2-3 times with a
celluloid ball.
9. Playing Defensive Players
I played against a chopper and a long pips blocker during my ball testing
and there was a greater level of consistency with the plastic ball from the
defensive players. I felt that the defensive strokes weren't able to produce
as much spin, but they were far more consistent in returning offensive
shots. I also found that it was difficult for me to generate enough power to
be able to hit through them and so I had to resort more to playing strong
placement and make as much variation on the ball as possible to try and
force errors.
10. Speed/Power Differences
With the plastic composition of the ball and it's slight size increase, the
plastic ball is certainly slower and tends to feel heavier when you first
play with it. This is more evident in attacking situations. I did find that
rallies lasted longer once I was able to get a better feel for the ball. One
thing which was particularly interesting was that it felt easier to return
attacking strokes, particularly when blocking and countering close to the
table. With the slower speed of the ball it seemed there was a lower margin
for error even when taking more risks. When generating my own power I had to
increase my weight transfer and play a little faster through my core and
arm swing in order to achieve the quality of stroke that I felt was
satisfactory. While it is difficult to generate 100% power strokes, the ball
is very comfortable in the 60-80% range for looping and making attacking
plays.
Conclusions
To really adjust to the new ball you need to get out there and start playing
with it. A lot of errors that I made were down to small adjustments and not
the actual ball itself. Once I was able to increase my weight transfer and
stay closer to the table, I felt much more confident making my attacking
strokes and adjusting to the lower and slower bounce. This aspect of the
game was easy to adjust to, the big task lies in perfecting the trajectory
height of the ball and achieving good spin in the tight game elements, the
service and long and short pushing game. With some variations and angle
adjustments as well as altering timing, I was able to make enough
adjustments to keep the ball low to the net and difficult to return. These I
deemed as being most important for matchplay situations. So overall the DHS
3 Star Plastic Ball is a very close rendition of the celluloid ball, while
a few adjustments are required it is a great quality ball and one we will
soon get used to with enough practice.
