If you are rusty or have lost some of your timing, playing doubles sets is not a good way to get your groove back:
- You are dependent on your partner to some degree
- Dubs points are short and not many rallies
- Playing sets can be stressful if you're not having any success
My advice would be to set up a singles hitting session with someone around your level. Get out there, hit, get your timing and groove back, don't stress, have fun.
The rest will follow.
