I was about to start a new thread but I think this is the one that has more tips on long wire walkers.
I just started learning to do them, im focusing in the first part, the boomerang and I just wanted to add one light if you are strugling wiht it because I just noticed...
The thickness of the rope is really important if you whant to do a boomerang with a taiwan top (tuoluo)
The rope you get when ordering from kostas is great for target but not for boomerangs... is almost impossible! the top doest come back!! But... if you use a thicker one (just a little bit thicker) the boomerang will work.
I checked many many videos and I noticed that the taiwan top top players use a rope a little bit thicker rope (even for target)
With a super thick rope I finally managed to do the boomerang start...
