Pass-through.

Lost a nice 6 point this year due to no pass through and heavy blood trail gone south after 300 yards.

If it's a high shot (like mine - deer was close), then it won't make a good blood trail for 2 reasons:
(1) you only have one high exit hole and (2) the arrow can partially clog the exit. Mine was single lung
and the damn deer still got away after half a day of tracking.

Also, if you aren't getting a pass through it is probably not as good a shot (unless quartering away
and burying in the off shoulder).
