RE: The idea of a Non-passthru..
Get the biggest mechanical you can find. I'm also shooting a fast light arrow and I'm shooting 2 blade Rages at them. I figure if I connect and make a good shot, hopefully it won't go too far.
Look at the Fuse Strut Busters, a lot of people in the shop are buying these to use. They are designed to kill penetration. We also have some Rocket Hammerheads on clearance.
