Brush contact practice

Hi Alois and Jeff, i was wondering how can i practice a good brush contact in your paddle and rubber of course. I have tried my topspins, they are well but the problem is that i hit them good mostly when they are slow into my side but when the ball is going fast depending long on serves or blocks i cant have a good topspin spinning contact. What would you recommend for this? oh and my finish position is in my eyebrow has improved, Thanks! 

Hi George,

I am glad that your stroke is improving.

WHen the ball comes to you faster you need to have more of a vertical stroke to get a brushing action.  Because the ball is travelling fat it will sink into your rubber quickly so the vertical action will help you to get the brushing action.
