It depends on the site.

For sites that clear bonus on the basis of simple raked hands (i.e. any hand counts as long as it's raked - e.g. the Party raked hands method) then FL is fine. Shorthanded FL is quicker.

For sites that clear bonus based on points awarded according to the AMOUNT raked (e.g. all iPoker sites such as CDPoker) then play PL/NL. Omaha & Omaha 8 are particularly good as these tend to have high pots.

For sites that require contributed raked hands (e.g. Absolute, Bodog, UB, Ongame) you really need to play Stud, or any other game with antes.
