I have both of these tournq's. The CAT came with the Tactical Operator's Response Kit: http://www.officersurvival.org/collections/ifaks-medic-kits/products/tactical-operators-response-kit. The SOF-TT came with the Downed Operator Kit: http://www.officersurvival.org/collections/ifaks-medic-kits/products/downed-operator-kit. First, let me say I think both of these are great products and carry each of them (at different times) with all confidence. The CAT is around $7 more than the SOF-T Wide. Both have locations to write the time of application on them. The CAT comes with infinitely better instructions (it is two-sided with color pictures). Online, you can find great videos detailing both of them. The CAT has a plastic windlass; the SOF, a metal one. However, they both lock into a plastic windlass stop. Therefore, I don't see a lot of benefit to the metal of the SOF. Remember, I have not used these for real. In taking them out of the packaging to try them out loosely, I noticed the SOF stitching has already started to come undone. The part that is coming unsewn holds the windlass in place. This is with one winding of the windlass approximately two and a half turns: This is unfortunate, but does not effect the usability of the windlass or the tournq. It does make me concerned for the overall build quality. Here's the biggest pro the CAT has over the SOFTT, the CAT is much smaller when stored. The thinnest I can get the SOF-TT, using the recommended storing method is approximately three inches. The CAT is about 1 5/8 inches. That's a big deal for most of us without external vest carriers. Storage lengths are near enough not to matter. The CAT has 1.5 inch webbing while the SOF-TT has one inch webbing. The SOF-T Wide has a 1.5 in webbing, like the CAT. The SOF-TT storage width is approximately 1.5 inches, same as the CAT. The one thing I like about the SOF-TT is the part that causes the storage problem. I like the spring-loaded metal clasp and the tightening screw. I trust the mechanics of it better then the velcro on the CAT. In use, I doubt it's any different than six of one, half a dozen of the other. If anyone has any questions or wants additional pics, let me know. For the record, a paramedic friend of mine really likes the CAT. He hasn't seen the SOF-TT, in person, yet.
