I was tossing at 12 o'clock for a kick serve and 1 o'clock for a flat serve.
The new coach then told me to try to use basically the same toss for kick and flat (use a very slight tossing difference). He said if my toss varied too much for a kick serve, I would be giving the spin away.
I had thought it wasn't a big issue if the returner knew a kick serve was coming but I can understand why the coach thinks its important to disguise the spin.
