Experimenting with styles: suggestions?

[Guy F]

Read a Cardplayer column by Scott Fischman a while back about using cheap SnG's to experiment with different styles at a level where the money doesn't become an inhibition. Seems like an obviously good idea, one of those 'Duh! Why didn't I think of that?' moments.

But what constitutes a "style", other than the very broad definitions of tight/loose, passive/aggressive? What I'm looking for are some suggestions for experiments. Somehow I'm having trouble getting my imagination started on this. Thanks for any ideas you can offer.
