Today I've saw both of them and found that their price are similar......... I found that the 21sp is a bit head heavy,would it affect the control of the racquet??? I just don't know which one should I choose............. thanks for helping........
I own both and much prefer the cab21. It has a much slimmer shaft and I find it a lot easier to play backhands. In comparison, the cab20 feels more clumsy and I find the balance is weighted too much towards the handle. But this is a personal opinion.
