Has anyone ever tried using tools and crampons, it would make almost anything possible, and look mighty cool too, you could climb brick walls and stuff as well as pulling crazy figure fours on skyscrapers and stuff. only down sides are that the equipment cost a bit more than free, the equipment damages the buildings a bit more than skin (interesting side point – what would buildering dry tooling ethics be, does scratching up holds really matter) and dropping your tools could hurt passersby slightly more than a chalk bag
