Great post. Slices in general and returns in particular, either are knifed low over the net and at the ankles of the server or ar popped long or as a sitter to the netman.
Some days you hit the former and others the latter. Nellie's advice to try to be more aggressive (on an already aggressive serve) as the solution is good advice, though sometimes difficult to accomplish.
