i'm not sure if i have the classic or just beal booster III...i've got the one with the 7.2 Kn impact force...it is by far and large the softest catching rope out there. Its skinny, and does get fatter over age. Beals also kind of flatten out if you fall a lot. Its an excellent rope, not as light as some others out there but i have enjoyed climbing and falling on it since 2008...I havent had any issues with mine. Primarily climb on gear so i dont do a whole lot of falling. handles great clipping bolts as well but a pain in the ass to boing on as its so damn stretchy!
