A review of the Switchback by Thyrm and Costa Ludus by Firelance Media... "In a nutshell, the Switchback is a good product that is worth purchasing and for about $20 you can try it out and not have buyer’s remorse. I really like the thought that went into the design and I’m going to keep one on my Fury for now. I’ll probably find myself switching it with the Raven Clip depending on the day.

Another product that came out of collaboration Thrym with Chris Costa of Costa Ludus... "The SwitchBack dials your full-size SureFire Flashlight up to 11 adding a pocket clip, and optimizing ergonomics for searching and shooting. After taking a look at all the options available for flashlights and weapon-lights we realized that there was a big disconnect: Weapon-lights are great for shooting, but they create a lot of liability when searching.
