Familiarity: I've put it through the wringer
Yes they are a little on heavier side but it makes it that much easier to get great sticks with just a little flick of the wrist. In fact I mostly haven't experienced any of the deflection issues mentioned in another review. If you take your time and swing deliberately and accurately you shouldn't have a problem. They are a little uncomfortable on lower angle stuff but you do adjust pretty quickly, definitely use the rubber "snakes" that come with them. I simply cut them to fit where I wanted, then wrapped them to the shaft with climbing tape. When it comes to mixed routes though, these tools really stand out. The narrow profile and flexible shaft give limitless placements and incredible security torquing into cracks. Overall I'd recommend these to just about anyone, except for someone who has never swung an ice tool, or never plans to get on mixed routes.
