Limit MTT, strategy question.

[Mig]

I play quite a lot of limit holdem cash games but when it comes to limit MTT I'm not doing great.

If your plan was to win a big limit MTT would you go for a style having a higher variance, slightly looser than optimal cash play or you would stick with a tight strategy and solid play ? It seems to me that the successfull people in the few tourney I played were quite looser than I am.

Could anyone refer me to any discussion on that matter ? I would greatly appreciate.
