lately ive been looking up kick serve vids since topspin is the only serve i cant do yet and i noticed in every video it shows them teaching from the ad court is it because its easier to do it serving from ad or is it like wicked hard to hit a kick from the deuce. and ive gotten the adding spin part now im trying to ad the pronation but then it seems like i get slice or it just hits the net any tips? Working my way up to learning it.
