Pingskills backhand topspin

Hello Pingskills,

I guess it is a stupid question but I found that I can do the forehand topspin quite smoothly, but on the other hand when I try to do the Backhand topspin I can't get a strong grip on the racket.My bat seems to fly off my hand in the direction of my swing. If I hold the bat too stiffly, it gets really difficult to get the swing and to get the bat swing through whereas if I hold the bat too softly, it flies off my hand.

Is there any way to get more power on the topspin alongside more spin. Would really love to hear the solution from you, since backhand plays a very important role in a rally and is equally as necessary as the forehand as you said.

With regards,

Fayad
