It depends where I'm at...
Indoors, with a table, Triumph or Card Under Box... Outdoors, without a table, Dirty Stinkin' Ape in the Middle or A Simple Sandwich, a medium sized audience, Bad Inflence, Indoors without a table, Invisible Deal or perhaps Aces + All Over the (Dis)Place - it depends how I feel, but there are generally a small group of effects for each situation.
