My first thought is that outrageous is probably not a good idea. Even though I don't count, I got booted at the El Cortez in Vegas on my last trip. Granted, they are a notorious "sweat shop". I was spreading 1-10, and winning. But I played less than half an hour, and was only up $50 when they backed me off. Part of the reason was that I had a friend with me who was very inexperienced. His actions were so "over the top" that the casino may well have thought it an act.
There is some good information in Blackbelt in Blackjack about what the casinos look for in a sterotypical counter. So what you'd want to do is be as far away from that as possible. I also think there is a similar chapter on the Blackjack school offered online at bj21.com. Here are a few of the items that come to my mind from those lists:
Males are more suspect than females.
Young people are more suspect than older people.
White people are more suspect than African Americans
Americans are more suspect than foreigners.
People who don't drink while playing are more suspect than those who do.
People who don't toke are more suspect than those who do.
People who wear caps, sunglasses, etc to shield their face from the cameras are more suspect than those who don't.
People who look extremely casual are more suspect than those who look a little more "dressed up".
Basically, your best bet is to look like a vacationer. This can be helped along if you ask the pit boss about restaurants, talk about the sites you've seen, how crowded the toewn is, the weather, what is on your travel plans, your significant other playing slots or shopping while you're playing, etc.
Keeping the sessions short and not playing through a shift change can be valuable tools too.
However, to me, one of the things that makes the most sense of all I've read is that counters typically don't think at all about the way they play their hands, but think a lot about placing their bets. Gamblers, on the other hand, think very little about how much they are betting, but think long and hard about their playing decisions. So the best thing a counter can do is to make betting decisions quickly and pretend some ignorance or indecision in strategy moves. This can be especially useful if you're making strategy changes based on an index. If you always mull it over for a minute before you hit your hard 16 against a ten, you won't draw any attention when you decide to try it the other way because "It hasn't worked when I've hit it."
