If I understood this correctly, whereas youth has U-11, U-13,U-15, adults have Over-30, O-35, O-45 as their age brackets

In youth playing "UP" is for added challenge and playing "DOWN" is cheating

For Adults playing "DOWN" is for added challenge and playing "UP" is cheating

I would love to see an O-45 team play against a U-11 team (non-contact of course)
