I never consciously thought about it until my coach asked to see which grips I use. I was shocked to see that I use a semi-western grip for both strokes. He said that a SW grip for a 1hbh is better for high balls, that such an extreme grip might be difficult to use on low balls. However, he said that some players can make it work for them. So I'm going with this route; it works for me. But really, is this a bad habit?
