C.A.M.P. Radion Ice Screws: Filling the Frozen Niche

Because of these drawbacks and its high price, I would categorize the Radion as a go-to niche screw. Though Radions will never become the backbone of my rack, I also will never leave the ground without a few on an extra cold day.
Pros: Sharp teeth bite well in cold ice; solid, low-profile arm offers great crank leverage; unique thread design fractures less ice; floating hanger allows leader to clip into a partially placed screw.
Cons: Long crank arm gets caught up on textured ice; awkward racking; expensive.
