Play it slowly, as flips and even hands where you have flips and even hands where you have a 60% advantage, will probably not be worth it at the end. This is because, if you consistently risk your stack in these situations, there is a good chance you will bust on one of the occasions. Also, the 1.5k or 3k chips you earn won't matter to much in the long run. I believe that grinding early in the tourney is better as you can gain a significant amount of chips in the long run, without being as risky.
