A couple of my friends and I will be hosting a large tourney in July, 50-70 people, with a $50 buy in. Anything I should be concerned with or certain rules that I need to make sure are clarified. Basically the only thing I am worried about is the blinds and starting chips. We plan to start around 2 or 3 and would probably like to last around 6 hours, but don't want people who are playing well to get blinded out all of a sudden. What is a good progression. Thanks
