Fixe Alien Lite cams have made great efforts to lighten the regular cams while maintaining CE certified test strengths. Newer trigger pulls allow for smoother functioining, easier cleaning, and lighter weight. Slightly longer, more supple webbing runners help with cleaner placements that allow for minimal drag. The cable pull triggers now allow a greater variance in size range with less trigger pulling. These cams are going to have more possible placements than the already very light and versatile Aliens.
