Hi all, I am trying to get the above shot right to to improve my game against power baseliners. Hard to explain, but here's an example from federer: http://www.youtube.com/watch?v=RWwiqsI7duk When hit correctly(?), it looks pretty good as the ball lands with speed in the service box at a wicked angle, catching out the baseliner. Problem is I can't do it consistently, shanking quite a number of balls. Any tips on getting it right?
