You can't possibly describe the efforts of a top player in 11 words.Dima tried for one year and it was difficult for him
What does this even mean?
Also, a 1% decrease in successfully landed shots, for a top player, can make a world of difference. An amateur wouldn't even notice that. Same for 1% change in spin, 1 degree lower arc, etc. So if it's "too difficult" for him, well, I'm sure he would still wipe every single sub-top player off the table. (the premade bat challenge comes to mind)
And then there's the result: Dima will continue playing with what he's sponsored by.
As an amateur, I'm all for trying out. As long as a player realized they're playing with *very* different equipment, trying out can really only broaden one's horizon (or empty one's wallet lol).
I wish I tried out different blades and rubbers a LOT more 20 years ago... Well luckily I can actually afford more of it nowadays, but it might have helped me to never quit TT in the first place.
