1.8 should be enough but it depends how good you are.
Its always hard to recommend stuff without seeing what your technique looks like.
Best way to know is to ask your coach or more experienced players at your club.
Go with Mark V. 1.8mm is a good beginners choice. Don't overthink it.
You can generate more then enough spin with it, if you have the correct technique.
After your Mark V is worn and done. I would recommend to go for a more modern rubber.
Mark V is a little bit like Hurricane and has no catapult.
In training you should get balls with very little deviation. To train your technique and swing. Switch it up in training if its wanted in training like training for float or under spin etc.
In match play you should watch the opponent and then follow the ball with your eyes until you hit it...
D05 is very good at mid distance. High arc very spinny you can really go forward and the ball goes on the table.
D09c you need a lot more body and legs to have the same result but if you hit it correctly the spin is outer worldly.
D09c is the best rubber for counter top spin, where as D05 is...
To me it looks like he has weak forehand open up. Maybe spinny but very slow. And in a top spins really if it gets changed from backhand backhand to his forehand he doesn't seem ready and his counter is often not dangerous enough. This leads to him having to go to his lobbing game or running...
I never said he lost because of his forehand style just pointed the style out. And said he lost because he has weak forehand and that his forehand was exploited. Every match LSD lost, was because of his week forehand. At least it looked like it to me.
Never said i know better then his coach...
Amazing win from anders i am still pissed i can't watch wtt live in Germany after R16 i think.
LSD has a very weak forehand for a Chinese player. Anders exploited it really good. LSD doen't use his elbow at all he has very similar motion to Harimoto. If I would he his coach there would be a lot...
Slowing things down and dropping balls short are very important. Also for me right now I get caught in the elbow to much, so for me it would reading the opponent better and being more efficient in deciding if I want to play forehand or backhand.
I also think it is very Important to have a plan...
I used Butterlfy free check pro and it annoyed me. Kept pulling bits from the rubber even big holes.
Switched to DHS No.n15 never been happier. Great glue.
Same for me i have also two but they are the same. The back up racked I use to train our kids team so I have some degree of being used to it and my main racket which I use in training and matches. Also having two rackets for traing the youth and one main stops me from having to glue new rubbers...
