What is the Best Thumb for hitting spacebar?

[Fame]

What is the best thumb to hit space bar? Should I alternate between Left and Right thumb depending on which key was last pressed.

 

I am trying to become proper keyboard typist. As I am learning to practice touch and type using muscle memory, I have managed to reach 30 words per minute but I am noticing my speed slows down on some keys when using my right thumb like when I am pressing Y, Spacebar in quick successions . I tried testing my speed hitting both  Y and Spacebar with right index and thumb got speed of 6.8 keys per second, then I tested hitting Y with right index finger and spacebar with left thumb that gave 9.1 keys per second. But the problem is my right hand is my dominant hand and I automatically use right thumb to press spacebar but my speed increases with left thumb but have a weak muscle memory when using left thumb.

 

So should I work on increasing left thumb muscle memory or should I keep practicing with right thumb? I want to achieve a speed of atleast 160 words per minute. What's the best way to achieve that. The people who type over 150 wpm, do they use left thumb, right thumb or both?

Look at your keyboard - is the spacebar dead centre or skewed to the left or the right? There's your answer.

IMO, people use whatever they are comfortable with.
