Above all, keep it low and vary the serve. If I find a weak spot I will come back to it a little more. I have a pretty nasty backspin serve but it is use it too much the opponent will catch on. My practice partners are use to my serves but I can still catch them off guard by varying them.

I like my YEO c-pen. I am normally a shake hands player but I can fool a lot of people that I play c-pen with my YEO. BTW, I think the playing c-pen is as natural as playing shake hands and RPB is natural too.

Everyone does but you are looking at this wrong. Why tell your friend you will make a rubber likes yours for a small fee.

NO! if the paddle is still accelerating at impact then it hasn't reached the maximum speed and the maximum speed. Any acceleration acceleration after impact is wasted energy and will delay recovery as now you have to decelerate the paddle. You want to hit the ball with the maximum paddle speed...

It is easier to get a faster rotation if the inertia is lower. It requires less torque. Reducing the radius of rotation reduce the inertia and the torque to achieve the same angular velocity. The faster angular frequency is offset by the smaller radius so the paddle speed remains the same though.

The whole point is for the bicarb to break down into a gas. CO2. That would leave the Na residue behind. When you let sea water dry it leaves some salt behind. There is no vitamin D in the light. People synthesize vitamin D from the UV part of the spectrum. Sun light will make LP pips more...

So many opinions. An endless supply of opinions without real data to back them up. Since getting real data is unlikely, one must really ask "what can I do with rubber A that I can't do with rubber B" Chances are you can do some things better with rubber A and some other things better with...

I didn't read the pdf too carefully. It looks like a hoax. What happens to all the residue left behind in the sponge? It isn't good if the residue stays in the sponge. It will make the sponge heavier. Salt crystals left behind won't help. Also, some sponges are closed cell and others are...

I used googe translate. The file is too big to copy as text.

So many opinions and no facts. The main benefit of tacky rubber is that you can brush more thinly and still grip the ball. Once the ball is gripped then that part of the ball will travel at the same speed as the topsheet.. If the top sheet stretches and snaps back there will be more spin than if...

when you hit the ball at the camera, I could see the Magnus effect on the ball so you are getting good top spin. Also, you loops were low.

The big difference between tacky and non-tacky rubbers is that the balls will grip with a much lower normal impact speed than with non-tacky rubbers. Most of the time the difference is little but when brushing the normal impact speed is low. I have sometimes felt like the ball has slid of my...

Show me an equation that shows that tacky rubbers are spinnier. When doing a ghost serve using non tacky rubber, you toss the ball straight up and move the paddle horizontally quickly face up. When the ball touches the rubber the rubber there is no force so there is no friction but eventually...

I wonder if anybody really boosts their rubber if they know it is going to be inspected. How do the people or machines that do the inspecting tell if the rubber is boosted by the factory, as some people claim, or by the player?

A lot depends on the SP. Not all the SP are the same. Some have more grip, spin and/or speed. What I like is 802-40 1.8mm or even 802 1.5mm but these rubbers are much different. 802 1.5mm is easy to play with and allows you to make consistent shots because it doesn't react much to incoming...

Based on mass alone, the bounce is theoretically different but the difference is so small because the mass of the ball is small compared to the mass of the table. The surface of the table will make a bigger difference. A 10mm slab of slate will be very fast because the slate will absorb very...

Rakza 7 is my main FH rubber. It does everything well enough and is very good for close to the table play. I buy mine at tabletennis11. I use the buy 4 for the price of 3 deal and I buy for multiple people. The Rakza 7 is more than good enough for most people. What it really come down to...

That would invalidate Giant Dragon Guard. I bought a sheet just to see what a Chinese "Anti" would be like. I was disappointed compared to the Japanese Antis I used at the time. ( Butterfly Super Anti, Yasaka Anti Power, and Nitaku Best Anti. I don't see why the antis must past this test but...

OK, but the collision isn't purely elastic. There is the coefficient of restitution. How do you apply force through the shot. Force is only applied to the ball during contact. You apply force to the paddle during the swing.

I have a strong back spin server. If you look at Ovcharovs' serve you can see he uses a lot of wrist and where the ball contacts the paddle is also important. That is the key. I was taught that by my first coach who had nasty serves. Since I am older, it makes sense to put more effort in to...
