In terms of design, I like the caviars ones because they have the same design as the Classic Jumbo Flap that you are planning to get. Between the two, the red on the caviar is rather dull, so for me it's out. For the black caviar one, it's hard to tell from the pic if it's the regular shiny caviar or matte caviar out this season... If it's the regular shiny caviar, then it's still in consideration - the plus here is that it will look like a nice set with the Classic Jumbo Black Flap. I can't tell if the hardware on the black caviar wallet is SHW or GHW though... If it's the matte one, it would be out for me.
I love the look of the patent one. Is the CC metal or crystals? If it's crystals, there mght be a possibility that the crystals may fall out with use. While the patent one looks attractive (Ok, I admit that I like shiny stuff. LOL). But personally I wouldn't go for the patent because I'm afraid that if I am not careful and it gets scratched, the wallet is pretty much gone. I read on the forum that there's no way to refurbish scratches on patent.
For the red lamby, I love this red color. It looks like a nice red and gives off a nice pop of color. so, if you are not the matchy matchy type of person (whether color or design), this red lamby would provide a nice contrast to your Black Boy, Black V flap and forthcoming Black Classic Jumbo flap. The design of the red lamby is nice too, although I prefer the caviar design because of the similarity to the Classic Flap look. Thus, it depends on which factor is more important to you.
I read on this forum that lambskin can be refurbished, while caviar and patent can't be refurbished. Although caviar is rather durable, over time, it is possible that the corners may get smoothend and there's no way to "put back the pebbles". For lambskin, it is more prone to scratches, but if the scratches are light, they can be massaged out with a leather cream and your fingers and they will be gone or less obvious, and overtime with usage, the wallet will develop a nice sheen to it. But of course, you must be mentally prepared to see scratches now and then, and have to try to massage them out and live with those scratches that cannot be massaged out. Oh yes, one more concern that comes to mind is the potential for color transfer. I read on the forum that some people had color transfer on their red lambskin bags... I read one post where someone was able to get rid of the color transfer with the Meltonian cream, and some others failed. If you decide to go ahead with the Red lamby, I would suggest that you read the maintenance threads.
HTHs.
