I use longlines made out of PVC coated braided steel cable with 1/2 inch sections of aluminum tubing crimped on the cable every 3 feet to secure snap swivels to anchor a Texas rigged deke, and egg weightts crimped on the cable spaced every 6 feet.
I wouldnt use steel cable to Texas rig dekes due to the stiffness of the cable, but it works like a champ for longlining dekes. I actually prefer longlines now instead of free floating dekes.
Do you ever get the feeling you're being watched? Because if you do, I'll stop doing it.
