Question re: Berkely Vanish

I just bought some 8 lb. berkely vanish, and hoping somebody can tell me if this flourocarbon line stretches at all?
When at Spray lake, I usually use braided line like fireline because of it's non-stretch quality to detect bites in 100 feet of water, and I'd like to be able to use this flourocarbon stuff there, but worried about stretchiness like with monofilament line.

Thanks!
