Audioquest slate, bedrock, MITs Spkr cables......

I have been seeing the bedrocks and slates, and Mit's selling at resonable prices lately, and want to try a pair.
Any opinion as to which I should try?
They will be bi-wires, running a pair of Infinity cs3007 cresindos.
I am currently running anticables, and just want to try something different on the cheap.
Other cheap contenders, rocket 44, indigo blues.
I have a bunch of decent ic's, but not enough speaker wires :(
Not having tried any of these, I am just fishing for opinions.
Which would you buy?
Many thanks.
