4.5 or 5.0 singles? BIG serve (SwingVision)

Zack (white shorts) and I (Black shorts) have played a few times in doubles but this is our first time playing singles, and it didn’t disappoint. We are both currently 4.5 NTRP players. Zack is a great guy and a great player it was a ton of fun to play him. I wish we could have played more but my right arm was in a ton of pain so i decided to call it quits after one set. when the video changes over, we pick it up at 3-3 in the tiebreak. Let me know what you think!
