re: Poker & Bubble Trouble
With freerolls, the key (which I believe you have found), is patience. There are LOTS of fish, so just wait for the premium hands and build your stack. As you reach the final third, the player pool gets more skilled (as they have lasted this long in the tournament), so it is time to change gears. What gear I change to will depend a lot on my stack size, and my opponents. I like to steal lots of blinds if possible at this stage. If my stack is very large, I play much more conservately, and continue to wait for premium hands.
