I actually check mine, though not a thorough "Twist, flex, feel," I do check mine with each shot. I generally gently wipe of any excess foam, and as I nock the arrow, I always tap the arrow on the riser, checking to make sure I don't have an odd vibration. I've caught 2 bad arrows this way over the years. Pretty simple to just tap the arrow on the riser, if it sounds like the tip is loose but it ain't, you've got a problem!!!
