$5. five person bubble strategy

[captainjack40]

On world poker exchange they have five person sng's where top two payout at 70/30. In harringtons 3rd book he advocates playing extremely tight towards the end to get in the money now I know i should loosen up in this format but should you rather go for the first and bubble out more or keep playing it safe and try and get 2nds. Thanks for any help or suggestions.
