I don't want to be contrarian or mean spirited or anything of the like but it appears you have invested a great deal of money in your system save the Syrah which is a bargain. Nonetheless pride of ownership appears to be important to you. If I am correct simply buy the most prestigious (expensive) cables you are thinking of. I Think the top of the VD cables might be the ones. You know even if the FIM sound better it will never match the level of investment you have made. I would also recommend the Dreamweavers from Jena labs man are those impressive.
On the other hand with my much less expensive but serious system also using JM lab speakers but the lesser Electra 936s. I did a cable shoot out. I had been using a rather inexpensive Phoenix Gold Biwire just copper. My pal brought over some high caliber cables I had amassed some serious cables but not as expensive as the ones you mention,e.g. Audioquest Midnights a previous long time champion , A silver coated copper biwire, Coincident top of the line etc. We listened objectively and there was absolutely a clear winner . It was of course the least expensive the Phoenix Golds!
I would seriously stick with the FIM if it makes you happy. I would experiment with less expensive cables if I were you. You may find that they are really better, maybe not I don't how many you auditoned, but don't discount them unless you are sure they don't make your sound the way you like it.
