You don't need both. If you shoot 3D or spots, I would go with a peep but for hunting, a kisser without a peep, gives you some advantages that last 1/2 hour before dark. I shoot up to 30 or 40 yards as well with a kisser as with a peep. If you are just trying to get speed, I would just put a 1/2 turn on your limbs as the gain won't make or break you. Speed kills only if you hit what your aiming at. Don
