OTI marked jigging line is great. So is JB, Tuf-line and Varivas.
Using the knot instructions that come with powerpro is just asking for trouble. When jigging you need a 10 - 15 ft section of mono or flouro as a topshot to the spectra. There are many ways to attach the mono to the spectra, some of which depend on the relative diameters of the lines, but all of which are a matter of opinion. Here are some spectra to mono knots for you to search for:
Mid-knot (my fav)
Page Ranking-knot
GT-knot
Reverse Albright
Albright
Worm (or yucatan)
I always use a heavier topshot than the spectra. To connect the heavy mono to the jig, I prefer the San Deigo Knot, while the other popular option is a Uni.
Hey, what is a Page Ranking knot?????
