I pretty much feel the same way as you do NL, but I purposely from the beginning did not demand he use such and such or nothing... he needed to start learning and developing the fundamental things... and he could learn them with an ALL+ or an OFF+ blade.
He needs to learn touch better, and he is, even with his equipment we would both like to see him go slower on the blade. Even with the rubbers I would like to see him go medium on FH and softer on BH, but the rubbers he has are still suitable and capable to make use of feel. They are not so bouncy on low to medium impacts.
He likes to spin the ball or better yet, develop more ability to spin the ball... and if You, Der_Echte and Scoobie Sergey Tsos all say it is easier with Nate's Koto outer wood blade and those rubbers to spin heavy and slow when he wants, then he may be even more inclined to give it a try for 6 months. He is already interested. I already gave him two more suitable blades.
His larger issue right now in tournaments is the mental performance aspect. If he is able to do enough tourney matches to not feel scared or stressed or pressured or tight, he will perform closer to his training level.
Right now, he performs 300 points less level in tourney matches then his training level. That gap will get less as he does more tourneys. he is fully aware of it and does not like it at all. He does not want to let anyone out-work him to get there, whatever and however that entails.
In the next month he will do at least two tourneys and has the Big Tourney goal of May 2023 888 Teams championships... that is the tourney he really wants and will peak for... then later (maybe a week or so later) - the Meiklejohn Seniors. By then, I think he will be a lot closer to performing where he should... and he should do very well at Meiklejohn Seniors vs that crowd. I have seen them, I know LDM7 will perform well there. They do not spin well nor block heavy spin. He just needs to return a serve and spin the ball to win vs them.
He is already defeating players 300 points above his level (even when playing tighter than tight can be) in sanctioned tourneys... I think by the time Meiklejohn rolls around, he will be winning 1400 and 1500 level players and get his rating near thee. An exact ratings goal is not the goal...
... I told him early on that if he trained a reasonable amount (like 1 hr plus lesson a week for 1 - 1.5 years) and if that coach could not significantly raise his play level, like a few hundred points, then the coach failed. That is the measurement. There should be a night and day difference in playing... and there already was early on by anyone's measure.
