I know that with everything else going on I can't handle more then 2 so the idea of 1 on the 1st and then another on the 15th works for me. As for the design I think it should be up to whom evers turn it is.
Now my question is does the person whoes turn it is pick both blocks or should we go to the next person for the second block.
If we go to the second person we could forseeably can get through the list in 1 1/2 years instead of 3
