For my tarp ridgeline I picked up a pack of MSR reflective guyline. It has an uncut length of 50' of 2.5 mm golden/reflective line, and 8x figure9's. Not a half-bad deal. I really liked that it was an uncut length of line, so I wasn't limited to precut lengths like other kits. The gold colored line is also visible during the day, which is handy.
