Blocking at the bounce of the ball vs the peak

Is it better to block at the bounce of ball (barely after the ball touches your side of the table) or at the peak of the bounce. I find that when I block at the bounce, it gives less reaction time to my opponent, but when I block at the peak of the ball, I can control the block better against heavy topspins.

But I am not sure what type of block should I use.

which type of block do you recommend me to use.

Hi Luke,

It is easier to block the ball at the top of the bounce so that you have a better margin for error over the net.  If you hit the ball too early, the ball is low and you need to lift the ball up and over the net.

You are right though that blocking earlier gives your opponent less time.  

You need to trade off between these two things.

Start with a flat block and then as you progress and if you get time you can put a little topspin on your blocks as well.
