I have the main agent use Opus, and have it always call sub-agents running Sonnet. That's the best setup I've found. I turn off compacting to be manual, makes it easy to find a stopping point and write all context out to an md file before compacting. First prompt isn't very important to me. I haven't found i need special phrases. What matters is how context heavy I can make my subagents.
