I decided to swap my first spear tubes and try out the ROC buckle. They feel pretty good and they lock into place securely. The ROC buckle big difference is that it locks in and out of place in one direction and the distance needed to separate the two pieces is shorter rather than having to pull the entire length on the first spear tubes to break the connection. But this is a very small difference and doesn’t mean one is better than the other. My one gripe is that they came damaged. They had cuts and scrapes / an area that looks like something had snapped off. Wear and Tear isn’t a problem normally but these are suppose to come new. Also the hooks that attach to the cummberbun and placard were bent in as if they had been crushed. Which made it annoying to attach. I don’t know if this damage comes from before or after it left the warehouse so this should be taken with a grain of salt.
