Power all 6. If you decide to try other configurations, remove a chain. If it doesn't perform the way you want it to, put the chain back on.

If you do omnis, remove any drop. 6WD drop+omnis on the corners = spin city, because you effectively have a 2WD the entire match with the resistance of ball casters or less. Having omnis on one end, or having 4 omnis on the floor, provides slightly better traction.

Regarding the leadership vacuum:

If the team has no direction, somebody needs to step up and provide direction. That could be a mentor, could be a student. That person needs to have the final say on a design, but should see what the team thinks and why before making that design. If that person is you, step up and do it. If someone else is doing it, let them step up and offer to help them. Even if it's keeping the team focused on, "We need to do X, Y, and Z", someone needs to step up to leadership.

For next year: Team Handbook. Seriously, it'll save this type of situation happening.
