Difference Between Live Tourney and Online

[PSU046]

I have never played in a high stakes live event, but I have played in a few higher stake mtt online. I was wondering what was different as far as the hand people will typically show down the first day and how that may differ from online events. Another question is what are some of the better online qualifiers for high stakes mtt tourney's you have seen and what are the best strategies to employ. Sorry for the multipronged post.
