Yes, I agree, a slice serve gets hit around 2 o'clock (8-2) and kicker will be coming from (7-1) unless you toss way to the left, then it might be 6-12. Flat serve just gets hit at 12 o'clock with no spinning motion, just some snap down, so maybe (12-6).
I am going back to hitting more flat serves as my back gets tired over 3 sets hitting so many hard spin serves. Anyone know what might be causing this? I do hit 90-100mph kick serves now so they do take alot out of me over the course of a match but I get them in like 60-70% so going back to the flat serves may hurt my game since I only get about 40% of flat ones in at 100-105 mph.
