Here is a pic of my first 4 teir cake that I used the SPS with. I was extremely please with it. The only issue I had was my cake tiers were not quite 4inches tall, so my DH had to cut a tad bit off the pillars using a saw.
I highly recommend this system and I will definately use it again. Thaks to all of you for you advice.
I like SPS too. It takes all the guess work out of it. That is a STUNNING cake BTW!!
