Personally next years contest should run the same as this years. We'll take sign ups to a deadline, we'll ramdomly choose teams through a drawing so that all teams will be different. This gives everyone a fair chance as well as getting to know new members. It is very unlikely that all teams members will remain here for next year plus we will see an increase of participants.
Personally I like the getting to know new members reason. Plus if all the members of the winning team do not participate next year how do you pick someone to go on thier team.
This is obviously not just coming down to which team is shooting the biggest buck but more which team has members who have the time to get out and hunt. With around a 100 average score big doesn't mean win.
The winning team will prob. be a team that hunts alot and that would give them a very big advantage over all the teams next year. They would have all year to plan and encourage each other vs a team that is put together right before season.
I would go direct opposite of keeping them together and say they all had to be on different teams then you would have ten teams with a winning member from last year talking about how good it is to win this thing.
Regardless I am in I have had a blast and enjoyed getting to know my team members.
