An easy way to do it:
Seed the TOP 4 in each bracket by last year's placings. Simple.
(e.g. if the bracket being seeded was a Novice division, last year's Novice placers would take precedence over Intermediate placers, etc. If both wrestlers placed "5th" in the Novice last year, go by team points they scored last year to break the tie and so on)
It would add on more time for the administrators, of course...and I know it would be a Pain but it is an option. You certainly couldn't have a seeding meeting, Oh lord! (talk about a mess! and the time it would take! and the policemen that would have to be in attendance to keep the fighting to a minimum!)
