Fran used the word *prone* - so it s a clear answer! she said that it "COULD" be a criticial point. And she s very right- if you don t have a perfect timing, it s very easy to fall into this *curling issue* by executing this technique for a grip not perfectly.
That it works for many strong players is a fact-and noone here said that it would be a bad idea to *use* it. It s just not that easy.
@Fran : have a great day Mylady
