What size? I'll probably only be in 4 person teams, on the temperate glaciers of the Pacific northwest. I was going to pick the 19cm just because I assume longer ensures a better "bite" but the 22cm might be overkill. Any advice for a newbie? Thanks!
The rule about ice screws is that the base of the screw needs to be flush with the ice to be safe and effective. So if all you have is 22cm screws, you could be in trouble if you encounter shallow ice and can't protect it. I'd get a couple 19cm screws, 1 22cm and 1 13cm. It's pricey, but when it comes to ice you don't want to cut corners.
