If there is a high risk of a team being pulled at short notice from playing one round (Thus two teams not playing), it would probably be safer to make sure we have a thin spread of players from all teams.
For example, I don’t think I would start with two premiums from one team.
EDIT: So looking at my team, I now need to weigh up ...
Macrae v Bont
Kelly v Whitfield
Docherty v Cripps
