In reply to The Ex-Engineer:
I used a few stubbies on the Orion Face and Zero Gully. I think they were no more than 6 cm in length. My climbing partner had brought them back from the States, though can't remember the make.
On the thinner sections I used them on I thought they were OK and using them meant not having to tie off longer screws. There was always the thought, "Well at least they'll slow me down a bit". They are best treated as marginal gear, just like any other marginal gear.
I would definitely use them again and carry 2 or 3 along with a standard ice rack.
Cheers,
Rich.
