How long will they last?

I'm interested on hearing how long some of the "natural" materials used in building crappie structures have lasted before they have had to be added to.

I used to be able to get cypress slabs which I ripped into 2 inch square stakes. I caught some nice sized crappie just the other day out of one of these stakebeds. I think I built this bed in '98. The stakes seem as sturdy as the day I put them in.

I've heard that oak will last about 10 years. I don't know how long pine will last but I figure it's not as long as hardwoods.

I'm thinking about driving some larger diameter bamboo in as stakes. They would definately be easier and cheaper to get. I just don't know how long they would hold up compared to wood.

Let's hear from some of you guys that have been building beds for a long time now as to what materials have lasted longer for you.
