RE: Up poundage, new arrows???
paka, I also shoot fingers and it sounds like you may need to fine tune you set up not increase weight. You have a matched set up and plenty of kinetic energy and speed. Any wobble or disturbance in arrow flight will reduce energy on impact with your target. The arrow must come off the rest clean with no up down or side to side movement. When releasing the string with a tab or glove there is a side kickon the string. This means that when your arrow reaches the WB it is impacting the side of the rest and interfering with flight of the arrow. My suggestion: trash the WB and shoot a magnetic rest with a cushion plunger then bareshaft tune your arrows and you will not only increase penetration, but also speed and accuracy.
