I was taught with these so I stick to em.
Thats analogous to saying you learned to shoot on a .22 rifle, so you stick with it despite other better calibers.
But...In this case the one you learned on is the best on the market. I use the same. Gen4 is nice to have but the previous generations and the Wide are excellent at full stoppage.
If people reading this haven't taken their tourniquet off their kit and applied it and checked for lack of radial pulse, they are wrong. There are multiple tourniquets on the market that are ineffective and can be combat deadly.
