Just throwing this out there for any input. I am baffled and not sure what is going on. I have a Mathews Drenalin LD that I absolutely love and shoot like no other bow I have. This bow is a dream to shoot and so stable. I have recently changed strings on this bow and can not get the full weight out it that I had before I changed strings and cables. I have the exact brace height to spec as well as my axle to axle are to spec but the bow normally maxed out at 71 lbs and the most I can get from it now is 64 lbs; which is plenty but I am totally blown away by this and cannot figure it out.
