When getting to the table I start off by playing tight.. and watch the action.. If I think playing tight is profitable (loose table) then I will stay there.. However I will adjust.. But like you said about good players will notice this and fold when you are involved in a hand.. I kind of look out for players like this and try to set up a good bluff against them .
To me, if you wanna mislead the table to your style, it's better to start loose then tighten up.
Generally, when faced with unknown villains, players will assume you have the goods until you show that you're likely being aggro. Then it's time to tighten up but remain aggressive.
