The Late Starters League options for setting up the league divisions

Option A:  Teams would bowl either: a 5:00 PM shift or a 7:30 PM shift.  Each team would bowl on two lanes, one team per pair of lanes.
 
Option B:  The league would have two divisions: The first division would bowl the odd weeks and the second division would bowl the even weeks. Each team would bowl on two lanes, one team per pair of lanes.

Please select the option that best represents your team preferences.
