I did hear it said by someone - maybe Vandersteen - that if anything the wires used in biwire should be the same as each other I guess to avoid any cable induced differences. Mine are not the same but compositionally so similar that they might as well be
Where do you buy the raw silver cable in teflon though? Links?

Cable induced differences? In the crossover region?
That I would have to hear... I think you'd need to compare a course power cable to a fine wire to hear it... But, there is the crossover region with overlap. Thing is, the drivers already have their own character in the crossover region and only so much can be done to "voice" these differences out of the speaker. Often dispersion of each driver for given frequencies will differ which can have even more pronounced effects than SPL differences (which can be compensated for). Distortion of each driver through the crossover region is all a biggie. Yeah, you might have a miniscule effect on over-all voicing, but I bet any change would pale in comparison if you got a mix-match cable set that synergized well with the individual drivers. YMMV.
In any case, that's a big maybe. But the ability to use different cables is a plus in my mind. Using the same cables offers less benefit.

I've never purchased from that seller. If you google "teflon insulated silver wire" all kinds of goodies show up. If you're worried, order a few feet first as a test, and see what you get.
I agree with you mostly but was just repeating what I read about it - will try to find the source again. I suppose if you believe in different cable "character" then it is a valid thing - again here I am referring to two different types of cable used for the two different bi-wire runs. True that it would be mitigated by the crossover and internal wiring which of course is "common" in any case.
Also raises the issue that bi-wiring may have some validity but that the level of the system has to be high enough to notice it which might suggest that dual post sets "trickled down" to lower end speakers that probably arnt good enough otherwise to have it's benefit be noticed - but it was a cheap way to make a system seem higher end
I'm gonna do some other experimenting and A/B and doublecheck my thinking that it benefited the first time around. Also will check out those cables you mentioned. I had a line on some DH labs silver coated copper that I still might get - are supposed to be great for the modest price

You may find a stout cable on the midbass has a positive effect on damping factor (and bass response) that outweighs any negative affects in the crossover range.
I've done simulations with different cables and how they affect crossover curve shape (Q) and statements about two different cables causing *significant* response changes are exaggerations at best. I'd call the response changes miniscule at best -> under 0.1 db. Many here claim to hear 0.1db changes, I cannot. Maybe I am deaf! ;)

I have I think a 12 gauge on the midbass and a 14 on the upper posts - not that I bought them that way but it was what I had around to use and figured the lower gauge goes to the upper frequencies - but still a stout gauge compared to charts showing minimum cable sizes given my runs are just about 12 feet.
I have not experimented much with different speaker cables. I think the differences exist but are likely exceedingly small between basic OFC copper of thicker gauge and anything "better" - or maybe something like pure silver will sound "different" but not necessarily "better" which is another feature of the life of diminishing returns. My bro in law recently tried some Nordost Vahalla with his ASR and Quad speaker setup and said improvement was definitely noticeable but that the cables cost the same as a new Mercedes...
