Hey guys
Thanks for the reply, even tho the most are off-topic with Viscaria and Stiga.
I am still unsure if I should stay with limba or try out other thinks. I used a short time ma Lin offensive and disliked the quick release of the ball from the raquet. What about carbon as outer or inner layer? Will this destroy the "extra time release effect significantly"?
My answer is: the only way to find if softer outer (e.g. Limba or Hinoki) or harder outer (e.g. Koto) suites you is to buy some blade and play with it at least 20h. This can be typically done in between seasons (if you have 2x2h trainings per week then one month is already good time to find out). There are many people who like one and not the other but as both groups are big you will get suggestions which suite their game not yours. And it's not about the game style and stroke technique only, it's also very much about the feel and that's nothing you can find in our advice.
I did the same, tried two blades with Limba and two blades with Koto and Aniger, the outcome was clear: I need softer feel for my topspin, especially from the BH. It cost me some money but it was worth it. And you can get decent blades with pretty much any composition of wood and artificial layers from Aliexpress starting at ~20USD (actually less but in the range of 20~30USD you will get better quality which is usually on par with most of Eur/Jp brands)
Then if inner or outer carbon/arylate layer makes your game better is another step. Outer ply mostly makes the "dwell time" perception while layers below are giving speed/power and also how much the whole blade flex and damps or holds vibrations. Again you can get decent blade in price range of 20~30 USD so give it a go. My outcome is that unless I will get much more time for practice (like at least 3x2h a week and with sparing on my or higher level) I will probably be fine with 5 or 7 ply wooden blades forever. EJ virus will keep striking back so I guess I will buy some more blades for experiments but I wouldn't be surprised if this conclusion stands. Most of players who are below 1700 elo in Europe or 1800 elo in USATT are probably the same case.
Btw. there is one more view to this: people who are playing on professional or semi-professional level says that change of the blade isn't the problem, if you have certain foundation and you train properly you will get used to many things. However that takes time in order of months. Testing blade or rubber during one training (like Dan and others are doing in their reviews on youtube) is one thing but really finding what it gives to you and what performance you can achieve with it is totally different. That's why most of serious players don't get EJ strikes very often and if they really switch the blade it's 3-4 times per career (which takes like 20 years and longer). So many couches recommend to maybe experiment in some period but then simply choose and stick with your equipment for years and rather work on your agility and technique to make perfect combination with it. And for people who don't have time and money (and maybe even skills and expertise) to experiment simply stick with the best thing they used so far. there are many high ranking players who are playing with 20-y-o material, they survived all the changes in ball size and speed glue ban and they just go on. In my low division many players still use Sriver rubbers and they are able to serve and spin incredibly. I have no idea how they accommodated to new balls and maybe they still use speed glue (no one will check on this level) but it tells me that maybe equipment and hours I spend reading forums like this isn't the important part of TT
