Regal Supreme perhaps?

It was introduced in 2009 I believe and it's on my list. It's not that similar to Fireworks I guess, but it's a 28" x 43" sport of Krossa Regal that's supposed to have the lovely upright, vase-like structure of KR but a much wider cream margin than other KR sports before it, such as Regal Splendor. Some of the photos I found of it make it seem small and wimpy but they must be babies.
