Does the spin come from the blade or rubber
Equipment
Benzene Chiral Asked 7 years ago
Hihi Pingskills, I'm rather confused about what is responsible for spin. Chinese philosophy claims spin comes from the blade, while Western, from the rubber. Who is right? I use Reactor DJ200 blade, with Friendship 729-5 inverted rubber on one side and Friendship 729-755 long pimpled on the other. I tried to generate spin on the inverted rubber side but the amount spin I generated is simply very little. Is it my configuration problem or just my skill? If it is my configuration, what is better? If it's skill, how to improve?

Hi Benzene,
The main factor for generating spin is the rubber. The blade contributes depending on the speed. The slower blades will tend to give you more spin because the ball is staying on the rubber longer. The faster blades mean the ball will come out quickly and not have as much contact time with the rubber.

Thank you coach!

Wait, is it speed or flexibility of blade that determine time of contact?
Andy Zhao Posted 7 years ago
It is the flexibility of the blade because it's the dwell time of the blade that can influence the spin.
Rohan Keogh Posted 7 years ago
The speed of a blade is created by a number of factors, the primary ones being hardness and flexibility/stiffness. Both hardness and flexibility of the blade impact on the dwell time achieved from the rubber and hence the spin. The DJ200 is rated as medium for both hardness and stiffness. The Friendship 729 -5 is rated low/medium tackiness and medium hardness so unless you have a particularly thin version you should be able to generate moderate spin for that set up. It sounds like you should be concentrating on technique before looking for alternative equipment. Check out the PS videos on generating spin.

I've watched the video of Match Strategies playing as a chopper, and saw the need to vary backspin in a chop. How do we vary the backspin?
I also watched the video about contact point for maximum spin. I did that too and the spin was still weak.
PS tabletennisdb someone commented that Friendship 729-5 lacks generation of spin. Is spin solely dependent on tackiness and hardness?
So I can't conclude whether it's the problem with my technique or equipment.
谢谢！

Benzene, it is a combination of blade and rubber (probably 70-80% rubber) that will determine the spin. So that reviewer's comment was likely specific to their blade rubber combination. You could find a blade with zero spin rating and still generate good spin with the right rubber. Your combination should not be holding you back, unless your rubber is old and 'dead'. How long have you been using it?
The two technique elements, as Alois explains in the spin videos, that affect the amount of spin are the fineness with which you brush the ball and the speed your bat is moving through contact. The more you 'cut' or 'brush' the ball, the more spin you will generate, the faster you do that, the more spin you will generate. Practice getting a finer brushing contact first, then increase the speed of your stroke.
