Sounds like Tennishacker is saying if you vary your serve during a match, it is not sporting. I totally disagree. Hitting shots that your oponent cannot return, or force weak shots from your opponent is a GREAT TENNIS SHOT.
I suppose tennishacker thinks that a Major League Pitcher should only pitch one type of ball, because if he changes from a fastball to a curve ball, that would be unsportsmanlike, right?

Sounds like your ability to control your serve places you in the 4-4.5 range, your opponent seems to be a lower rated player.
Your strategy will work against lower rated players, but will not work with 4.0 and higher rated players.
When I play matches (match pressure), I always try to play my best, always looking for ways to improve my game.
