OOAK Table Tennis Forum

Hi folks

I made a test with a lot of long "tacky" pips rubbers at the ball machine in my garage. the amicus 3000 plus was set to the highest possible topspin. My intention was to find out how many backspin the different rubbers can create against haevy topspin.

I played the most rubber in this video with a thin spongs (0.5 - 1.0) and I tryed to make allways the same movement for the strokes.

So, here's the video http://www.veoh.com/videos/v542467gHSRZhnJ

Greetings

That is VERY impressive Martin, and such a big range of pimples you've tried!

Although I'm a little surpirsed at the results... i would have expected some thing like the nepune, which is quite a grippy pip, to have less spin reversal unless you brush it quite hard...

How did you come up with the numbers? Was it your own judgement, or did you have a way of measuring it?

Can you summarise the results here?

Thanks a lot for sharing, and welcome to the forum!

Massive - start that archive Haggisv!!!

Neptune taking top-spot. Ohh thats surprising, ok gang we must discuss.

I am amazed by that actually. Neptune a tension pip has massive reverse spin more than P1R.

Hi folks

The numbers for spin are a judgement by myself. I rateted every ball and took the average for every rubber.

Here's a list of all rubbers in the video

MILKY WAY Neptun Long Aspect Ratio 1 - Spin 86
TSP Curl P1-R Long Aspect Ratio 1 - Spin 84
DHS C8 Long Aspect Ratio 1 - Spin 84
STIGA Destroyer Aspect Ratio 1 - Spin 84
RITC 837 Long Aspect Ratio 1 - Spin 83
MILKY WAY 955 Aspect Ratio 1 - Spin 83
DONIC Piranja Formula TEC Long Aspect Ratio 1 - Spin 83
RITC 755 Long Aspect Ratio 1 - Spin 82
BUTTERFLY Feint Long III Aspect Ratio 1 - Spin 1 82
TIBHAR Grass D.TecS Long Aspect Ratio 1 - Spin 82
MILKY WAY Pluto Half-Long Aspect Ratio 0.75 - Spin 82
KOKUTAKU Tuple 110 Short Aspect Ratio 0.5 - Spin 82
PALIO WP 1013 Half-Long Aspect Ratio 0.75 - Spin 81
JUIC Leggy R Long Aspect Ratio 0.9 - Spin 80
BOMB King Roc Half-Long Aspect Ratio 0.75 - Spin 80
JUIC PipsAce Short Aspect Ratio 0.5 - Spin 77
FRIENDSHIP RITC 563 Short Aspect Ratio 0.5 - Spin 77

Very interesting is that the half-long rubber Pluto and the short Tuple 110 create as much backspin as the Feint Long III

Thanks Martin!

All those rubbers had a sponge right? As you know the sponge thickness can certainly impact the results as well, do you still have that information? Would be worth adding if you do.

Cheers!

Hi all.

May someone explain me what does it means ASR (Aspect Ratio?) ?


Thanks

Read it as the pip height.

I think strictly it is pip height against pip width. 563 for example has very broad pips that are not very tall, P1r has narrow width with tall pips.

The results suggest that if max pip height 1.8mm (?) then the pip width will also be 1.8mm. TSP P1r has max. pip height that is legal. 'r' stands for 'revised' because it use to be longer but those naughty ITTF people banned previous legal pip height and TSP P1 became illegal.

In contrast the results say that 563 is twice as broad as it is tall.

I have never measured them although I thought that pips like P1 were taller than they were broad, but the results here suggest the contary.

The aspect ratio has a big impact on the behaviour of the pip and helps determine how rigid the pip is.

Awesome. Nice set up and HUGE spin....
I did the same 3-4 months ago......take a look..too bad I had only 2 rubbers at that time.

Actually MartinSpin is correct, the aspect ratio is 1.1 but use to be 1.3.
MartinSpin just rounded down a bit.

Imagine if you were a pro and had to cope with a transition of 1.3 to 1.1, thats a big difference and would really affect the behaviour of the pips (they can't buckle under the weight of the ball)

Hi MartinSpin,
Great test!!!
I have switched to LP from anti only about 6 weeks ago and am having a ball. I just took a guess and got Screw Soft. It has a 1m sponge. If I block a loop, it will reverse spin and send chop back but if I counter loop, it gives small top or no spin back.
I have not found anyone that has used Screw Soft so I have no idea how it compares to any other LP. Do you have any comparison?
I also have a question about "spin reversal". To me, spin reversal would be where you block a topspin and the ball skids off the rubber sending back chop. If you block with regular smooth rubber it sends topspin back. If you chop with regular rubber or LPs it sends back chop. Since that is what is the expected result, I would not call this "spin reversal". In your tests, you are chopping and getting Lots of chop on the ball. Is this considered "spin reversal"? I am just trying to get the terminology correct. I understand the physics of LPs.
Really enjoyed your test. If you can compare the Screw Soft to any other LP, I would really enjoy that. Might save me from another EJ binge.

Hi Speedplay,
LOL,,,,It sounds like you have a hole in your EJing, Screw Soft!!!! I think you should remedy this as soon as possible and get sheet. Then you will be a true EJ with no holes in your knowledge and can report your findings to me.
Make sure you try it on a fast bat as I will then have a good idea how it compares to others.
Thanks so much!!!!

I think someone should also get a sheet of pimplemini (because it sounds funny)
