Recommendations for flexible speaker cable

I've been researching speaker cables, looking for a cable that's flexible to allow for placement in a tight spot. Ideas that come to mind include Analysis Plus, Cardas. I'm trying to keep the total retail cost to no more than $400.
Any ideas? thanks!
Supra Ply 3.4 is very flexible and retails around $200 for a 10ft factory terminated pair. flat,flexible,reasonably priced
Kimber is very flexible and should fit your budget.
I'm using the Quicksilver Audio cables (, which come only in 4' lengths. Don't know if that's long enough for you. They are highly revealing, pure silver, thin and fairly flexible. Even on my horn speakers, they are not bright sounding. They are $340 for the pair, and I've yet to find a pair under $600 that is as honest and transparent.
Good luck,
