Thanks edt. you saved me some $ I was going to spend on an assumption.
I suppose I could run the 1/8" am steel up 6m and then switch to to q-power, not sure how the am steel would stretch compared to the opposite q-power line though...?
That's one way to do it. 1/8" am steel doesnt stretch too thick 2500 breaking strength -- q-powerline usually just stretches one time the first time you put about 300 pounds on it, after that it seems to hold, where regular kite line will creep in length over the years.
neither should stretch at all. I run 1/16th inch 1.75mm 800 pound regular kite line up above my safety system, if you run this thick amsteel above your V you will have unequal line lengths -- if you snap a line you can't just swap in a new set of lines -- mite be inconvenient.
