So, your bonded line tests STRONGER than two single 1" lines taped together?
At what point did I say that?

Individual tensioning of two lines and then taping them together means different pre-loads, different points on their elasticity curve due to the different loads and all sorts of stuff you can't account for. If done perfectly right they will share the load probably within 10% of each other (a guess) but I don't think anyone could A) get them perfectly the same pre-load tension without measuring it very carefully and B) Account for all of the variables at work as then you have friction between the two lines, tape that allows some slippage, chances of different elasticity characteristics if they are off two different spools (especially if they are different colors) and all sorts of technical crap I couldn't hope to account for.

I'll tell you what I will do though, I'll tape up some lines side by side and send them in to our lab. I'll post how it stacks up in comparison to a single line, a threaded line and a bonded line. Keep in mind though, in a lab you'll be able to tension both the same much easier than when your rigging off the side of a clif. Also, due to turn around time, this could take a month or more to get the results back.
