Hustle on the shuttle runs, and take your time on the jerks. No line touch on the shuttle runs. You are better off trying to do bigger sets on the shoulder to overhead (rather than having to do lots of extra cleans). Catch the jerk with ‘soft knees’ when you lower the bar so you aren’t slamming the bar onto your shoulders. You can use a split jerk or push jerk as long as you bring your feet together before lowering it. If you tend to shoot the bar out in font on jerks, make sure your shoulders are mobilized well, and that you aren’t going too deep into the dip portion. It should be short and explosive!
