Well since I started using a bow last fall all I have used are 125g field tips/broadheads. But with what I have read on forums and mags is lighter broadheads are being used. I have about a 55lb draw on my bow. I went to a shorter arrow and my speed increased. I now can shoot a 3 arrow pattern in a 3" circle at 25 yrds. I intend to use this setup this fall but I am planning on getting a new bow next year. In changing bows should I consider lowering broadhead wt for more speed?
