Hot humid weather...your best bet is a smooth finish deck. Even these decks will soften up and feel "sloppier" in hot humid weather but you won't notice it as much as with a card with a dimpled surface. Only problem with smooth finish decks is that they tend to be more expensive(not as much market demand) for a decent quality one. Look for Aladdin smooth finish if you want a similar stiffness to a Bike. If you want stiffer look into Carta Mundi (From a European plant), Piatnik Clubs, or Fournier 505s. Also...smooth finish wont fan as well as a dimpled finish...on average at least.
