I just checked the optimizer website, maybe they just released a upgraded version but they say it has 20-80 yards in its range of adjustment. That coupled with 48 tapes to put on it and speeds ranging from 260 to 410 fps i think it could work well. Since a crossbow bolt has a much flater trajectory using a slower speed may offset the difference to a first strike. I think that you can also make a custom marked tape where it would only be based off where your shots are being zeroed at. I'll hopefully get to see trinity's set up at supergame.
