blades I don't know how to tell you this but xbows are inferior, The physics are quite different, that is why you need a 200lb draw weight that still does not compare to a 60lb draw weight of a compound bow!!
To expand on the arrow thing, which arrow can you throw farther (by hand) a xbow bolt or a compound arrow (both same weight)? Also part of the equation!
I am also assuming that your 100 yard shots are with field points!
