I see a lot of guys asking about higher end indexes and everyone that shoots one has a favorite. I prefer the dual sear as they are like a mini thumb button and have crisp triggers, no travel. I would have loved to include the Stan strike x but they unveiled it only to never produce them and i wasn't a fan of the xtinction. The s2 is new and a damn fine release. It's comparable to the execution but with a better strap, more refined tension adjustment, and perhaps a tad bit better trigger but it's close. Everyone knows about the execution and execute. If you're a target guy, the execute imo is the best option. It's closed jaw, comes with a heavier spring if you want more tension, and it's heavy. If you're a hunter that shoots a lot the execution or s2 all day. Open hook style, the s2 has a spring on the hook and is a nice feature, web strap or global swivel on the execution only the web strap on the s2 which I prefer. They don't get as much tension as the execute but they get plenty. All three are great releases if you're an index shooter. Last and kinda least the trufire exert.....😶 Is it better than most cheaper releases, sure but it's not one of the three mentioned above. One thing I do love about it is the weight and fold back feature we all know from trufire. The tension adjustment is on the body of the release. You loosen a screw and slide it up and down and leaves a lot to be desired imo. The travel is on the trigger itself, you only have one trigger option with this release the others come with two that can be mounted in different locations. For the the price you'd expect more from the release itself, the packaging, and brief Chinese instructions. Obviously I'm leaving out some great options but I cannot speak to them.
