Bought a couple rolls of Cortland back in the day, but I only use it for the bigger rigs where perfection loops/whipped loops/welded loops are a bit riskier as Tailingloop suggests. Rio sells individual loop in 3 sizes, although I personally like to double nail knot my loops, rather than rely on that plastic tubing.
For smaller stuff and freshwater as you seem to be describing, just nail knot on a butt section with a perfection loop as suggested.
