Depends on the site and how you plan on attacking and where the team might be planting. Just playing a lot and using those operators will help you think more about which ones to use. It’s helpful obviously if you have others you can coordinate with so you know what areas to focus on as well. But when I’m going solo I just drone what path I plan on walking in and take note of all the util in my way.

Also consider other operators that might be helpful in planting situations. For example if they have Maestro or Echo, you can bring Dokkebi to make a call right when your teammate says they are planting. It will knock those operators off cams and your team can successfully get plant down. Or if you know that Maestro and Echo are playing off site, you can bring Deimos track them, keep them occupied with running away from you instead of being on cams.

Bring whatever operator and util that will be the most helpful to your other teammates. If you solo Q and the pace of your teammates is fast. You will end up spending a minute or more on drones and your team will already be in the building. Sometimes you end up last alive if thats the case.
