this isn't directly related to your structure question, BUT

played quite a few of these last summer.  Even the first few levels play super aggro, and super loose.

If your bankroll affords it, I would try and get chips early.  These tournies, were, reentries last year.  So the early chip up has major value, with the short levels and relatively crapshoot structure.

That being said, obv don't recommend spewing.  obv suited connectors and small and med pairs, have a ton of value in late position, and a lot of people play these tournaments as rebuys.  

if you're still in the tournament by the time, the structure starts making big jumps, just make sure you've chipped up, and exploited the tighter players and the Spewtards in the earlier levels.
