You ask pros and cons. I can give you one hunting experience that I had that made me switch to a full containment rest, and I willNEVER go back to anything else. Years ago I had a standard prong rest on my old bow. Well I had a huge bull elk barreling down on me. Something behind it must have spooked it, so it started heading right in my direction and didn't know I was there. All I heard was what sounded like a tank moving through the woods. I wasn't prepared. I had to drop my rangefinder on the ground and knock an arrow. Needless to say, my heart was pounding and I was in a hurry. So in a rush, I drew the bow back and the arrow just flopped off the side of the rest. The huge bull just ran right by me about 8 yards away. Needless to say, I was PISSED! After that hunt, I installed a Whisker Biscuit and used it for years with no problems and NO WORRIES. I just recently tried the QAD Hunter rest due to full containment, but also the benefit of no fletching contact or damage. My groups instantly tightened up compared to when I used the WB (not that they were bad either). Long story short, a lot of things can happen when you are hunting. I figureI would rather have the security of a fullcontainment rest over one that is not.
