You could also get Gastite and cut off the outer cover, but you'd be wasting money on that outer cover.

here is my first attempt at winding a double helix coil for my bokabob still. no kinks,

Welcome to HD, did you wind the coil freehand or follow one of the tutorials using a pipe to wind around?

I tried both the winding 1/4" copper and the corrugated stainless gas line. Wow, is that gas line easy to work with! The corrugations allow vapor to pass even when the windings fit tight against the inside of the 2" copper condenser housing. I did the double wound copper on a 1" OD pipe per several posts here, but flattened the tubing enough that it really restricts the flow. Used a 60" long stainless 1/2" OD (3/8" ID) gas line to wind a coil and it couldn't have taken me more than a minute or two, and zero kinks. I think the gas line is the material of choice for a reflux condenser.
