A newb here and am hoping to learn a few more things.
I used to have some no-name brand ice axe that I used for years (mostly as a trekking pole or glissade rudder) but loaned it out and never got it back. I replaced it with a pair of Grivels, an Air-Tech and a Monte Bianco (?) but never had a chance to use them due to life circumstances. Years later and I am finally getting to plan for some mountain routes (moderate) and realize I need an axe. Well I dug the Grivels out of the back corner of the garage and noticed the picks don’t fit the traditional profile of a mountaineering ice-axe. The Air-Tech pick is only 6” long, has an aggressive curve and teeth that reach nearly back to the shaft. The Bianco pick is 6.5” long with a flatter curve and less teeth. Here are links for both so you can see what I’m talking about.

I have an older M.B. with a steel shaft but the head looks very similar to the one on the new model. http://www.mountaingear.com/pages/product/product.asp/CMP/KNC-97950/cmpn/97950/store/MG/item/111890/N/0
When I look at other mountaineering axes I notice they have a much longer pick. My experience would tell me that a longer pick would make a more certain self-arrest in deep or loose snow but are the picks on the Grivels adequate for stopping 200+ pounds of me and my gear? I will certainly practice with them before setting off but thought I would ask while I’m sitting at home.
I’ve also noticed the Black Diamond Ravens have a different design with a head that looks more comfortable for the hand but the cutouts on the adze seem like they would make it less efficient. Any thoughts on this would be appreciated. If it helps, my plans don’t include any water ice climbing, just glacier/snowfield travel and the occasional steep mixed snow/rock route. Thanks in advance.
