15CVOSG, not everyone I know likes all this year's colors, but I do like all of them to the point that I wish I could own one of each. Since I can't, I was partial to the black/gold and Hard Candy. The Hard Candy is an instant head-turner. The black/gold lures you in then when the light hits the flames they leap out at you!
I was torn between these two bikes but leaning heavy toward the black/gold and was ready to buy until I heard the new carbon crystal was being released. Since the new SESG's are not selling terribly fast in my area, it seemed that I had some time to wait for the new carbon crystal color without a huge risk of being left with no option.
Now having seen it, the carbon crystal seems to have all the same accessory treatments/colors as the black/gold, just the tins are painted different. I would have been very happy with the black/gold, but I'm glad that I waited because for my preference I like the new carbon crystal over the awesome black/gold.
Sorry for the long answer to your question.
