You know, you might want to check out the HORSE structure on full-tilt. It is a pretty slow growth structure (and you can make it slower by adding a 20-40 blinds round before the 30-60).Actually, what I did for my mixed-games hat tournament (a new game was pulled out of a hat every 30 minutes, and the blinds structure depended on whether it was a stud game or not) was that I combined the holdem and stud limits from the Tex's TEARS format. You can check it my tourney rules at:http://dimacs.rutgers.edu/~pdreyer/HatTourney.pdfGood luck!
