I can rally, and hit good topspin on my forehand consistently and a pretty nasty slice that gives a few people I know headaches, but anything after a 10 shot rally I begin to get tired because of my anything but tennis body build (Im 6 foot and 210 pounds, more a football build), and I have to pull the trigger on the rally to end it, win or not, to avoid getting too tired.
I'm going to go out on a limb here and guess that you have never seen yourself playing for points on video. you would be the first 4.0 player ever that can consistently sustain a rally over 10 shots.
