They are both good broadheads, I can't speak personally for the Grim Reapers but I have a friend that uses them and really likes them(no O-rings or rubber bands). I personally use RM Snypers(2 blade) and have had remarkable success with them. Always get a great entrance and exit wound channel.Very sharp, low profile design, and the rearward opening blade system, which I feel is their greatest attribute! I give the nod to the Snypers, give them a try and don't be afraid that they are only 2 blade, they get the job done!!!:wink:
