Yes, and or you can wait, hesitate, a spec to hit the TS. Some, like me, would argue that you shouldn't give away too much information on the toss. Other might respond with "so what" we know its coming. Good players can generally hit most serves to different locations with the same toss.Neither shall the twain meet, and NEITHER is the best alternative!!!
Toss should be "slightly" higher than the strikezone of the serve. That means twist serves can have a slightly lower toss.
