In reply to CurlyStevo:
Thanks for the replies everyone, I did have a feeling that this instructor was making things up, it was at an indoor wall attached to an ellis brigham so I guess new gear is the answer to everything.
They do certainly bend and it's not an optical illusion, they are good for general winter mountaineering but I am finding they flex a bit more than I wish even on WI3/4, they are obviously still usable but it's slightly annoying as they were purchased to replace my manta's for ice routes!
I may go try some more on in some shops to get a comparison then report back!
