ok, i was taught to "hop" on your left foot when you finish your serve. however the other day, i saw some guy "walking" his serve. he served and didnt finish on his left foot, however his left foot remained planted and stepped forward with his right foot. so instead of finishing with his left foot down, right foot up, he had his left foot down and behind, and his right foot down infront. is this a good way to create consistency? since your not airborn and remain on the ground. btw both of us are right handed.
