Need some help on this. I currently have and love my Mathews Monster. I have it set at 71 pounds with a 29.5 inch draw and 400 grain arrows. I am shooting 318 fps with about 98 ft pounds kinetic energy. I hunt in the thumb of Michigan on my farm. I am comfortable shooting up to 60 yards as I can hit a 10 ring at 60 with all 3 arrows. I hunt a mix of woods and field. Now I want more fps keeping the same draw weight and draw length. Now should i go to a lighter arrow and gain more speed but lose energy. Or should I keep the set up I have? I want to get up to about 330-335 fps. i know I will sacrifice energy. What should I do?
