Has anyone got a good pocket/sleeve style device that hangs off your rack ?
I have seen the tool roll type ones on the market, esentialy a small tube would work eg plumbing tubing with a small cable tie ?
Sounds like Petzl flutes .
Grivel make one that you wear on your chest which I found really good, easy to get the screws out without faffing on the harness

Could probably make one yourself for a fraction of the price!
I can't imagine climbing a full on ice route with all my screws in one of those plastic racking flutes. Ice clippers are the way forwards and can easily take enough screws for a long pitch.
