Me at 2000
Me at 2200
Differences
Equipment: When i was 2000 i'm a stupid EJ. Playing with unboosted h3 where people get to block and counter my shot so much easier. At 2200 even tho i'm still an EJ, i've grown a lot better at boosting and gluing rubber. My shots are no longer easy to block/counter. I'm also richer compare to myself 6 years gold and afford myself a gold vis. Gold vs > normal vis by a mile. When you hit hard gold vis will sound like a stiga blade with "dong" while normal vis will sound like "pia" and goes down to the net.
Speed: In terms of absolute speed and physicality, I was faster and injury free 6 years ago. However, i am faster now in pong speed, after i serve i'll have these couple of mini steps while the me 6 years ago don't.
Serves: my serve was always good even at 2000 but at 2200 i make it even more dangerous.
Lower center of gravity: this is one of the most important aspect that upgrade my game (i haven't reach my peak rating yet, my rating went up 3 times in a row the past 3 tournaments). I don't standup straight like i use to. When I stand lower, the ball speed is also slower. The reason for that is when you stand up straight and look at the ball, the speed of the ball is how your eye observe it. When standing up straight you are observing the ball almost like perpendicularly. When you stand lower the ball is coming towards you at a lower speed thus easier for you to react. <-- i don't know if i explain this properly but whoever understand this point do help elaborate.
At the end of the day the biggest take away here is
equipment, it directly affect skills. I tried the whole suit of EJ like xiom rubbers h3 backhand etc... it just doesn't work. If you know how to boost then play h3 on forehand, if not then 09c. For BH just stick with BTY 09c or D05. Don't try those ESN trash. It hinders my level for years.
Just to illustrate a point, i EJ a lot and i swap paddle and try out with fellow club mates. Most club player's paddles are unplayable, they glue it bad, terrible rubber combination, bad weight distribution etc... HOWEVER, none of my coaches (most over 2400, had over 20+ coaches in a span of 7 years) paddle is unplayable. Almost all of their paddle i can use it anytime and play close to my level.
As of now i'm using vis gold, h3 FH, 09c bh.
