yea true, there are some risks ya gota take, and the more i think about it, if you tie in with a breakaway lanyard for positioning then you have the problem of it not being a second tie in point which ya need while running a saw. altho it seems that a lanyard thats sufficient to hold your weight safely could still be made to break before your doubled climbing line above you did? maybe in the future we will see something available, i almost picture something like a break away link you could put on the d ring where your lanyard attaches, giving you the option of clipping right to the d for sure tie off, or to the break away link when the situation was appropriote like a uncertain branch. i think for now i will just stay off any branch that doesnt have leave or looks questionable. luckly the two longest limbs i have to go out to cut back on my buddys tree are both pretty good size, about 14 to 16 inch where they come off the tree, i just worry a bit cause they go out maybe 20ft but i think they should support me, and the only parts that need to be lowered by rope is basicly just the stuff thats brush at the end, under 2 inch dia, the rest can just be cut and dropped. it is interesting tho that the article you posted the link to realy didnt mention any workable solutions to prevent it, just kinda gave general statements about lanyards and such that realy didnt have an effect on the accident in my opinion
