But I think this experiment is flawed by the length of the two lines that are being used. It all comes down to stretch, and with two feet of spectra (with no stretch) and two feet of flouro (that stretches a little), the flouro is doing it's job and the spectra is too. All of the pressure in your experiment is on the spectra, not the flouro.
I've heard people talk crap on Power Pro (power pop as some refer to it), but I've never had a failure with my two year old 65 lb Power Pro, works for me. Especially if it tested out on the scale at the shop, end of story.
