yuredingwrote a review of Petzl Attache 3D Screw-Lock Carabiner on March 10, 2010
This replaced my OP pear biner for belaying. Very light! It is virtually the same for most situations. However, the Petzl 3D doesn't always stay in the right position as easily when belaying a second up using a ATC Guide. This might just be me.
