I'm trying to identify who among my 3.0 ladies players would make a good singles specialist. We want 4-5 singles specialists, and I've identified 3 clear choices. That leaves two more. Once we eliminate players with poor groundstrokes or poor fitness or no desire to play singles, we're left with many candidates. How important is it in singles at our level to have a big first serve? Or a consistent serve? Or good footspeed? Or topspin groundstrokes? Or slice groundstrokes? A good overhead? Is it a deal killer if someone has a weak side (e.g. weaker backhand)? Or is it as simple as using the weaker volleyers as singles specialists?
