I agree with peg818. The one cake I had that sunk and cracked was a 16, 12, 8. I used cardboard circles and it sat on display for probably six hours. By the time we cut it I noticed the back of the bottom tier was collapsing and had a large crack going down it. Lucky for me hardly anyone noticed since it was on the back and I was serving the cake.
As I worked my way down the tiers while serving it, I noticed how soggy the cardboard circles were. The circle under the 12 inch had two of the dowels from the bottom cake poking up through it so the weight of the 12 inch was squishing the one below it. I'm amazed actually that it didn't look worse from the outside once I saw what was going on with the structure inside.
That experience taught me not to rely on cardboard. I now use foam core wrapped in plastic wrap, still use wood for my dowels and have not had a problem since.
Please don't get discouraged, cake stability is a common challenge for us newbies. You have the knack for making beautiful cakes, now you just need to learn the tricks of the trade!
