New Kevlar Supplier, Part 2
Here's how the Emma Kite line is shipped. The label is marked: "1,000 feet - 150 lb. - Twist".
Will this line be better than the stiffer line from The Thread Exchange? Time will tell!
My past experience with the stiffer 135 lb. line is it will last for about 20 flights before breaking, usually right above the engine mount. That's one reason I developed a "Replaceable Kevlar Engine Mount" CLICK HERE. If Kevlar is tied beneath the upper centering ring of an engine mount there is no way to tie on a new line once it breaks.
Emma Kites includes a snap swivel with each spool of line. I don't know if I can use this style swivel on a rocket but I'll hang onto it for now.
