In this article and this Outdoors.SE answer, the following use for stick clips is mentioned:
Having a clip stick means you can take a quickdraw out at a time. Just lower to the next bolt, clip yourself in to that quickdraw to take the weight off the rope (no need to untie). Use the clip stick to unclip the quickdraw above and bring it down. Repeat until you can touch the floor.
However the stick clip which I own is pretty long (57cm/1'10" when folded) and would be unwieldy to attach to your harness. Putting it inside a normal backpack would also be a bit inconvenient as it would stick out and you'd hit your head on it if you lean back. Additionally there's the risk of dropping it to the ground, potentially hurting your belayer.
Is there a good solution for climbing up with a stick clip?
