I plain old fashioned plywood and leave 'em dry and have never had a 
problem. Around here the biggest problem with forms is the hole around 
them collapsing and having to destroy the form to get it out.  
Exterior/treated plywood might work, but I've not had any problems with 
the concrete bonding to the plywood. Of course there will be enough 
concrete on it that you won't want to run it through a saw, unless it's 
carbide tipped.

OTOH if the hole is large enough you might be able to rent the steel 
forms although it takes some equipment to get them out of the hold. 
Course an engine hoist set across 4X4's might do it.
