I've seen this mentioned from time to time but never saw a thread on it. This was the lesson i re-learned the hard way. All this hype about RHS and spin, you tend to forget that you don't catch the sweetspot i don't mean s@#t:evil:. All i did was concentrate and hit the SP and i had no more use for excessive RHS. Even on my serve this helped with consistency,power, and spin i'd been missing on my serve since getting caught up in RHS. Such a simple thing makes such a huge difference.
