I am trying to really work on consistency of my groundstrokes and I am trying to add more net clearance for my basic rally groundstroke. I get away with hitting the ball down and flat for winners, but it hurts my consistency. I was thinking of a string or net that you can affix to the net as a visual and practice aid. Sometimes I start out hitting higher and deep at 75% power but then i crank it up and hit it flatter without thinking about it. Basically I am looking for net extender if that makes sense. I guess I could make one, but that seems like a lot of work. Thanks.
