Why use a line, make a cylinder.
You'll need around 7 segments maybe more. Make it 9 sided, then a apply a FFD 2x2 modifier, make the tip narrow.
Now apply bend modifier, bend it at 120 degrees on Z axis and then limit the effect so the top is straighter.
Now add FFD 3x3 and add some finishing bends that you need.
So in the end you're still working with a cylinder and can add segments or sides if you want it to be of higher or lower quality.
