If you're pushing the backspin balls into the net, you're probably just digging into the ball too hard, or you need to adjust the bat angle a little more...Since the 802-40 is quite grippy, it plays similar to inverted.
There was a really good article on hitting with short pips here somewhere...It basically talked about the contact point on the ball when hitting... against backspin you need to make contact at about 4 o-clock (where 3 o'clock is is right at the back of the ball). Of course you need to read the amount of backspin, and make some minor adjustment.
Hopefully our short pips players can chip in some more here.
