Yes... and no.
In smooth, parallel cracks these function great, both going in and coming out. In irregular crack sthey can be a pain in both directions. The noodle-ish stem can cause problems, and the doubled sling is not that useful. I'd rather just have a beefier single sling. These have a nice range, and definitely outshine the tech friends. But I would chose Aliens, C3s, Master Cams, and TCUs over these.
