They'
ll do the job just like any shaft if tuned for the bow. The reason they hit lower is probably due to two things. #1 they are smaller in diameter so are angled down on the rest a little more than ICS type arrows. #2 the shafts tend to be thicker walled and heavier than insert type arrows.

The biggest problem with the older protruded shafts with outserts is fletch clearnce with most shoot through or prong rests. This problem is pretty much solved with drop away rests. One other thing is that they aren't made much anymore so getting replacements and replacements parts could be pretty tough.

On another note, when the protruded shafts break they splinter leaving shards of carbon fiber in a wound channel. Eat these and your innards are in for some big trouble. How does going to the hospital for surgery sound?
Newer, ICS types usually snap cleanly if broken in an animal, but care should still be taken to trim away any meat around the wound channel.

Hope this helps.
