We have an answer, his left side of the bar broke, along with one of his powerlines.
Does anyone know any good high Y bar that are known as reliable? I am completely losing faith in core and looking for something that flies well with a core kite
you can retrofit most of low-V bars with something like this
flagging may work differently though, something to test separately..
Also on smaller sizes running 24m low-V setup will be almost indistinguishable from high-Y as long as you adjust the line lengths..
center lines on V bar would need to be shorter to accomodate for geometry change (so extra knots)
