Hi! I will be making my biggest cake this weekend, 6-8-12-16 wedding cake. I made a 3 tier cake last week and thought it was already heavy. So I am really concern about this cake since I'd have to deliver the cake assembled due to the details of the cake. First, will bubble tree straws be strong enough on the 16" cake to support the rest of the cake? Or should I use dowels, wilton plastic dowels, SPS? Second, what kind of board should I use under the 16" to support the entire cake? Would a regular cake board work? And how would one even lift this cake for delivery? Thank you so much!

SPS. Not regular board...make one from MDF/masonite. Yes, this is going to be extremely heavy. Two people should lift and carry.

For SPS would a center dowel still be necessary?

No center dowel necessary, there is not even a hole for it. Here is more info:

That's what I thought. Thanks so much for confirming. I just purchased them for the cake and also a masonite board. The cake will be covered in fondant so I hope I can measure the cakes to 4" and not have issues. I should have played with this on a practice cake first! Thanks again.
