I've been looking at a lot of jackets and whatnot online, and the jacket I've pretty much decided on comes with dual density armor in the shoulders, elbows, and back. Available for that jacket are CE inserts and GP inserts. My question is, what's the difference between these 3 types? From what I can see, it looks like the dual density is basically just foam that doesn't look like it'd do very much, CE is a more robust foam armor, and the GP is hard plastic with a foam backing for comfort. Assuming that's correct, is GP the best to have in a crash, or would the CE be better?
