Blind Stealing in Tournaments

[Precept2]

Blind stealing is one of the leaks in my game, and I understand that it's an integral part of tournaments. I play in a game with a few TAGs and a bunch of LAGs and LPs. I need your help.

Should I only steal in late position?

Should I wait until folded to me?

Should I make an absurd raise?

What if there are limpers in front of me?

Should I only steal a TAG's blind?

Do I need any kind of hand to steal?

All suggestions are welcome. Thanks.
