I'm trying to decide whether to go with inexpensive pressure-treated

kind of prefer the cedar option, but I'm unsure about whether it's wise to
go with cedar that is only half the thickness (hence, half the strength)
as
standard patio grade cedar. My concern is not about safety per se so much
as it is about structural rigidity, solidness, etc. I don't want it to
feel
like I'm 'bouncing on planks' when walking on the deck. Any suggestions,
advice, experiences? Thanks...

I finished my deck last night. :-) I built it with 5/4 radiased cedar
decking on base of pressure treated wood. The construction style is
floating dekblok with 2x8, 16" centers and I used deck screws to attach the
cedar to the frame. I'm confident for anything less than a mosh pit type
party that the structural integrity will be fine. I'm over 200lbs and the
cedar feels plenty rigid.
