Same here, but that's mainly because once I was sure I had enough chips to make the top 600 I stopped playing as there was no point in taking any risks, even with AA.
It was funny watching some players refuse to stop playing pots when they had a ticket locked up if they stopped, but then lose their chips and not get a ticket.
I remember 1 time a guy had over 110k in chips in one of the morning games with less than 6k players. In these games if you got to about 35k in chips you were pretty much locked for a ticket, even 30k might be enough, but he kept playing every pot and doubling short stacks up until he didn't have the chips to get a ticket.
I saw that many times, but that was the most obvious case.
When I knew I had the ticket in the bag I was folding AA and KK preflop so making the top 200 was rare as I just let my chips dwindle down.
