I think it`s well-arranged when I answer to everybody`s questions in an own section:
@haggisv: I have to agree with you that we have to see the material-question differentiated. Characteristics like the own strenght and the own playing-system play a big role here. One only wants to hold the ball with as much control as possible,the other one wants to make pressure and speed with the pimpled side.
In times of frictionless long pimples I only played pimples in ox.In these times we had our loved spin reversal which was stronger when the ball got the contact to the blade more directly.
Playing with pimples which have friction the difference between a thin sponge and ox is not that crucial.Both is possible for a game near to the table but I myself prefer the combination of an ox-pimple with a blade with catapult.
I am sorry one (and one of the few things) I will not talk about is what composition a "perfect" pimple for playing close to the table has to have. I am working on that and cannot give out my detailled knowledge here because other people read, too.
@RebornTTEvnglist:till now I enjoy this forum, too and I hope and think that this keeps going on.
@mynamenotbob:In times of frictionless pimples like Dr Neubauer and Hallmark the opponents acted more often with balls with little spin. Now it is nearly always possible to play hard shots and the opponents play more often.
Playing against such not so hard balls without spin it is very important not to let the ball jumping out when you want to play close to the table.Then the opponent has mich time to play against your not so fast ball.If you get the ball very early you make much more pressure to your opponent in 2 cases:
1)he has less time to make his position perfect
2)you can take the speed and energy of his ball and need not to make such a big movement where you yourself could make more mistakes.
If you were the guy in my course you can act for example with this sidely played ball, with the short "hack" or with the short "konter".
There are many ways to take the ball but as I explained you have an advantage whewn you take it very early.Another opportunity is to make a long defence ball but that is not what you want to as I think.
I for myself stopped playing professional playing because of healthy reasons around 1 year ago. Now I play more for fun and only see that I keep a quite good level because I love table tennis(there I am quite nuts) and want to see whats going on in the sport. Now I act more as a coach and in the table tennis industry.
@quelis:
OH, the last months I had to feel the results of testing everywhere. You always swear to keep your material but testing makes too much fun.
You see that something new works better with new material but something old runs worse.It is important to get to know what is most impotant for your style and to get your middle way.In my mind it is more important to make your strenghts more strong with material than to find the middle way where you can make everything a little but have no strenghts. BUT

it is also important to have no debility which loses your matches.To find out what`s the best for you you have to test nearly everything(different combinations and speeds)to get to know what your strenghts are.Many players have strenghts they do not know because they only played with one kind of material.I know I said nothing you did not know before.Please don`t hate me for that but I could not say better

That`s the reason we are all quite nuts material testers^^.
I do not think that you have to have a balsa blade to play successfull with pips close to the table. Playing with balsa rackets has a different feeling in playing many people prefer but other players hate this feeling.In my mind balsa rackets have one big advantage compared with classic rackets to play with pimples close to the tables.They often have a non-linear catapult.This helps you to play good offesive shots in combination with control in defesive shots.It may sound a little bit queerish to you but I saw many players who make much less mistakes with a faster racket. Playing with a nearly catapultless racket they had to make bigger movements to drop the ball on the other side.These big movements were the reason for mistakes because if the movement is wrong in one moment the ball does not find his way to the other side.
Having a little bit more catapult on the backhand these players only had to give a short controlled impulse to shoot the ball.Therefore I play with faster balsa rackets. Coming back to mynamenotbob they espacially support playing against spinless, slow balls and making pressure.
Your second question I have to leave here because of the reasons I telled haggisv. I hope you will pardon this
@speedplay:
As I said because playing on my own is not the most important for me in the future I have no problem to give away the weaknesses of this system...
there are many ways to go against such a kind of system but to give you better advice I need to know more about your own skills and style. Then I know what shots you use good and which way you could go.Your own style is very important for my advice.
