I'm still writing up my AAR and gathering information together from stages where I didn't take good notes. I was in the 3rd squad. On the opening ruck I believe 5 teams across the board missed the ruck. We got taken out by the last ruck for the day on day 2 by 15 seconds. As far as the packs themselves, I ran a mystery ranch selway 60 and it's just a size too big for me. I bought an XL and probably should have bought a L. Other than me buying the wrong size I think it held up great and did very well. Another guy in my squad had the same pack and he said he loved his too. My buddy ran his kelty redwing 44L (old style, not the new models) and he loves that pack. He'll probably get buried with that pack some day.
All things considered there was a huge variety of packs and participants there. Everything from a rifle slung over the shoulder, rifle packed up vertical and rifle strapped down sideways.
