The Victory arrows are ready for the Parkers. You will get a more consistent flight and a harder punch downrange. In the tests we were getting more f.p.s. at 30 yards, even though the arrow weighs more and is slower at the barrel. I know that may not seem to make sense.
Here is a little explanation, to help it make sense. All objects drop or fall at exactly the same rate. With the same basic size, the air resistance on each arrow is the same. So, air resistance isn't a factor in this case. Now, here's what happens, air resistance slows the arrow, momentum tries to keep it going, a heavier arrow will have more momentum but the same amount of drag(if arrows are same size, same fletching, etc), so the heavier arrow will slow down less during flight so it will have a slightly flatter trajectory and maintain it's speed farther downrange.
I know that it might seem that the Laser II's are a difficult combination to beat, but I think we've done it. I'm getting better groups with them.
