TT: Does the perfect setup exist?

What is the ideal racket setup for table tennis? Of course it's the one going for the highest price on the market right? The first question is a little like asking if there's an ideal home out there in world, just waiting for you to move into. I love watching home tours of various interesting houses online and some might even tempt me to say "this one" but there's always something about the interior design short of perfect, something superfluous, too artsy-fartsy or "not me" enough. (With the possible exception of this humble 58 sqm apartment in Seville; yet though I think it's perfect, I'm sure in time I'll find it too small). Perhaps it's like that for table tennis rackets too, there's no perfect, only as good as can be. Just as a good home / interior design would have to pass my 3 tests of Functionality (or architectural soundness), Taste and Character, I think the best setup has to pass these 3 ratio tests: Weight-to-Power, Power-to-Spin and Durability-to-Stiffness. You want it powerful but not too heavy, able to generate great spin but not be weak/soft, and you want durability but the materials, wood and rubber, to not be too stiff. If all 3 ratios are excellent, there would be no need to change setups any longer. But the joy of testing, feeling the solidity of a newly minted racket in the hand, the "sorry, new racket" apologies as you clumsily try to get use to it - those things would also be missed.
