highest stakes holdem online

[quadT]

so let me throw out this question:
What are the main differences between 30/60 b&m vs. online, and how do these discrepancies differ from a 100 b&m vs. online

My general observations: online players at this stake will bluff or semibluff-raise hands they generally would call/fold with b&m. but as far as i see, i don't see a big difference in the type of play the 30 game vs. 100 game. The biggest difference is that its nearly impossible to find a full ring 80 or 100 game (as someone earlier pointed out)
