How many coins do you deposit into MTGOX/Tradehill?

Those of you that do a lot of buying and selling, how much do you tend to keep in your wallet vs online at an exchange? Right now I have all my coins in my wallet (which isn't much) but I'm leery of dropping them all somewhere but if the prices shoot up to a good selling price, having all your coins that you are willing to sell in your wallet could slow things down alot, right? I'm just afraid that someone will walk away with all my coins. Maybe I'm being too paranoid or just missing something.

It's an interesting question because i'm having the same issue. Yesterday some idiot screamed on twitter that mtGox had been raided. It was a false message, but still. How reliable are these services, how's there backup procedure, how easy is the security breached. I'm having 50% of my coins stored at mtGox, for fast trading, because one hour delay for confirmation can be a real spoiler when seeing the exchange rate go up.
