Trying to figure out a team lineup. Four guys to make up two pairs: guy A: lefty, 5.0 guy B: lefty, 4.5 guy C: righty 4.0 guy D: righty 4.0 [rating used just to show the level they are at, not for USTA purposes] We'll play one pair that'll be 4.5, and the second 4.0. I've always thought that having a lefty in doubles was an advantage. So with that logic, putting two lefties together would sort of being wasting a lefty. Do I put out the two lefties together or put each one with a lower level player? Thoughts? Thanks in advance!
