That’s a pretty difficult question to answer — at least if you’re looking for specific suggestions. However, I think a good rule of thumb is to practice the techniques that you find most difficult. In other words, if you have a natural gift for playing fast single strokes but find that you often speed up when you play with a band, then use your single strokes to warm up at the beginning of your practice session, and put most of your emphasis on practicing time with a metronome. Of course, you’re the best judge about your strengths and weaknesses, so make your decisions based on recent experience.
I hope that helps.
