The number of pins isn't the "issue." The gain is that you have a trajectory so flat that you can easily use one-pin to 40, without having to play guessing games on yardage. Just point and click. As your speed hits the 300 mark, increasing - you start to see some really tight pin gaps. There comes a point where you can just take the pins off altogether. It clears up your sight window and makes target acquisition a lot easier. Likewise, if you shoot a slider, you're not fumbling around adjusting yardages and sliding sliders while your buck is walking away.
