Tried the Petzl Glacier Literide in Ellis B on Sat. Nicely made - good pick, wide adze and it has a proper spike on the end (pretty blue colour too ). However, it's very uncomfortable to hold - the depth of the pick (top to bottom) is too big for me to get my fingers around to grip properly.
So BD Raven Ultra has won - even tho' I would have prefered a proper spike rather than a 'cut off' point.
Thanks for all the comments.
I didn't need to use the axe on Sat. but was glad I had it with me. My route was along a SW facing ridge and most snow had melted. Would have been a different story on a NE facing route.
