Good point for me it was the same. I wanted to lose any doubt that the ball slipped because of cheaper rubbers or whatever else.IMO there is almost no difference between all those blades. All 6mm composite that play roughly the same. I think it's all psychological. I've tried many of them and they are always disappointing, all roughly the same feel, speed range, sweet spot (poor) etc. It's likely that the best players in the club can use a $10 blade to beat you.
Some of our juniors, who use pre-made bats and train 1 day per week for 6-12 months, have taken sets off other juniors who use $600 setups and have been training 4+ days per week for 3+ years.
That being said the psychology is an important part of the game. So if manufacturers and their sponsorship players have convinced you of the quality and importance of their equipment, it may be beneficial to you to just purchase it and use it, as you may feel more confident and it may remove any negative thoughts about your equipment during play. I suspect that more money has been spent looking for alternatives to expensive equipment than the expensive equipment itself.
Now I can focus on actually Training.
Also I bought the China Men national team dress that I liked with the dragon on the shoulder and played with that. It just makes me feel really good. Just psychological as you said. I think it's good to find things or change some things to keep you motivated and train more. Just don't go from 40° rubbers to 53°. Or the other way might be drastic aswell. As the end of the day all those blades work and it's just feeling. You should feel good about your equipment.
