In reply to UKC Gear:
It doesn't really compare like with like.
The Grivel Munro compares better with the Peztl Snow walker.
The Petzl Summit is more like the Air Tech.
Who is the comparison for? Beginners need more info (B vs T, pick shapes for different comditions) Wheras more advanced users need the caomparison to be more even. Why isn't each axe's blurb formatted the same way? Makes it a bit useless.
