I got the Echo, and done know I made the right choice! Have only give it a few runs, but its even better than my old Samurai. Improved jaws to lessen torque, and I love the trigger!
I have no doubt my Samurai would've lasted many more years, but, I didn't have a backup in case! The Echo has a buckle strap, my old Samurai had the velcro, and it's the only part that's badly worn. So the Echo is my primary now, Samurai rides backup! Both IMO, as quality a release as is made!
