Play cards

When you are scouting an opponent, how do you create play cards for the scout team?

Do you still hand draw them? Use hudl playbook? Something else?

Do you draw up every play you see on film or just highlight the most important?

Do any of you just stick to main running concepts (power, GT, Trap, etc) and just focus on defending those without doing new cards every week?

I'm helping this year and am responsible for a lot of this. In the past, I drew up almost everything. It took forever and the kids really couldn't execute it right unless it was a similar offense to us. Just wondering how others do it because I'm always interested in getting better.
