In reply to Chris Robson:
I got anti-balling plates for mine after a season of growing taller with every step and getting fed up of having to belt my foot withthe axe every 5 paces, and never looked back.
The only problem is that I got a Rambo front point kit for them for steep ice climbing purposes, ad the a-b plates don't fit when the Rambo points are mounted, so I have to fall back on duct tape then, which which works, but not as well as the purpose-made plates.
Personally, I'd spend the money and keep on using them, since otherwise they're a perfectly good, if rather old-fashioned, crampon.
