I notice no one is saying any thing about arrow speed here, do look at that a 300fps shoots reasonably flat for abot 30 yds if sighted in right. Now I have a barnett 150# it was cheap and I needed a short range xbow for shooting fish it shoots 240 fps and it would take a deer [and has ] or goat but you better be dead on with the yardage or the rainbow trajactory will cause a miss; now with the exocet or Ten point I sight in for 27 yds and any where between 20 and 35 is 3 inches up and 3 inches down and I just shoot over or under the cross hair and they are stuck right there . The other important thing about arrow speed is the fact that they can and will jump the string[Jump or duck when they hear the noise it makes when you shoot. if they are 25yds or under they dont hardly move with 300 fps arrow at 200 fps they better be looking the other way and not be already spooked.
Just a few things to add to your thoughts. Lee
