Well, there is part that is true, but you forgot something here, WANT vs. NEED.
I bought many blades, and to my surprise, they never made me a pro or high level player, but some definitely changed my playing style or gave me advantages, so i will never forget that factor, i was playing with cheapo all wood chinese blade and before it arrived i was using Jun Mizutani and Tenergy as i started last year, and what i found, that chinese blade+rubbers kept me in slow mode, while Mizutani and butterfly rubbers increased my speed, and i didn't say increasing speed means increasing skills or level, but it just jumped me to play in different style immediately.....
... actually, i gave my blades to some players as borrow, they play now as if they had training for months, it didn't change them to top players, but they all got confidence and became attacker and enjoyed playing much, in fact they hated the one they were using, so they went and bought something similar or same of what i have, and this is good thing, buying something doesn't really need to be for getting top level as must, but when you have something quality and expensive design look all will give you some kind of luxury or making life easier, belive me, not all drivers can buy or drive Ferrari, but if they have the money or budget and the freedom, i no doubt more than half of them will have those racing cars or even the top brands luxury expensive cars, so why not with blades?
My friend who i play with is still using my blade i gave him since 4 or 5 months ago, he never play with his racket again, and i kept it with him until he can afford or buy new racket for himself, and he himself told me how his skill improved significantly with my racket, and the kids i saw in the club in my town [not in another town] are not much improving since years with the blades they have, and they train for almost everyday, in fact i did beat them all and also did my friend, so where is all that training they had for years? But don't take me wrong, training is very important factor #1, but don't stop others from getting what they want/like just because it is designed for top 20 TT players or their skills don't match it, let them just gain skills through time and not by the gear.
