There are people who have that theory that you need to use the unforgiving equipment that will make it so you have to be perfect to use it and that is better for a developing player than more forgiving equipment.
The flaw in that theory is, what happens to a player who does not have the precise control of the blade face to make very precise contact on the ball, is this:
1) The contact is poor and the ball flies off in all kinds of directions that were not intended.
2) Then the player subconsciously messes with the stroke and the stroke mechanics become bad, because he does not have the control of the blade face to make the right contact.
3) What this leads to is THE WRONG KIND OF CONTACT and A COMPROMISED STROKE.
4) These bad habits become ingrained because, with a mechanically flawed stroke, less impact, the wrong impact, and some other things that should not happen, the ball does land on the table but the quality of the ball is not good.
What more forgiving equipment does is help you develop a good stroke and start improving the quality and kind of contact when you do not have the control of the blade face to make the precise contact needed for higher level, less forgiving equipment.
Try the first one (the one Freitas labels "Warm Up") on a wall. If you can do it on a wall very solidly, with a lot of control, then you can try it on the edge of a table.
Try the one called "Change the Ends". When you do it, you should be able to do it while keeping the ball rolling on the blade face and edge (NOT Bouncing).
Try the the catch part of "Grabbing and Punching". You are trying to catch the ball without it bouncing.
If you can do those three, you probably can develop the control of the blade face well enough to be using rubbers that require more precise contact soon. If those are hard to do, if controlling the ball and how you touch the ball, makes those a little hard, it means you still need to improve how you control the blade face when you contact the ball.
If you can really do the first one with a wall and do it for at least a few 100 hits, that means you have decent control of the blade face. If you are not able to do that, most likely, using some of the higher end rubbers that are more spin sensitive will mess up your strokes and make it much harder to develop good spin contact because, you will only be able to get the ball on the table with bad contact (non-spin contact) and while cutting off your stroke and making your stroke SLOWER....too slow for a good stroke and spin contact.
It is worth knowing, some of the Chinese tacky rubbers that are really good, help you create massive spin but are also very forgiving. Like H3, if boosted it and used something like that, it affords players the high end quality, while still being forgiving enough for a newer player to use it well.
