The way i look at opening in the quiver is... who cares. Thats just from pushing them to forcefully into the quiver. As far as deflection, i shot two deer at quartering away angles, one with an extreme quartering away and i didnt put it as far back as a should so it started behind the shoulder and lightly angled in finishing at the front of the chest i ended up with probably the worlds biggest entry wound and had it not been for that probably wouldnt have found her. The Blood was unreal and i was able to walk up on her and put a follow up shot to kill her. The shot i took was probably more quarter than someone should ever take and if i didnt deflect off the back side of that shoulder and still penetrated then i dont see it happening. I wouldnt know if mine did open in flight nor do i see how anybody would but i finished that doe at 20 yards with a bent rage that wouldnt close and it still shot straight haha. I will tell you that the rage two blade is on heck of a head and has converted me from a die hard fixed blade hunter. I would recommend them to anyone. I killed five with mine and the results are beyond impressive
