Ok.. Here is a thought.. Limit to 20 people ($1,000 a month). Pick the product to bust.. Do a random of names and the 32 teams. That will leave 12 teams "unassigned".. Run a silent auction for these teams, in which the money spent on these teams will roll into the next months break..
you could do this with 20/25 teams etc...
As far as peoples feeling getting hurt about not getting anything, that is part of the risk of doing these breaks, you win some you lose some. this isn't grade school.
