As always, I say match the tool to the job. Light arrows for 3D. Heavy arrows for hunting.

Light arrows and flatter trajectory help offset minor misjudgements in yardage estimation. Very important on the 3D range, where rules say you can't use a range finding device and all you have to go on is your own skill in yardage estimation. A few more points on the scorecard might put a plastic statue on your fireplace mantle.

For hunting though,if you keep most of your hunting shots within 30-35 yards, might as well go with the Terminator Selects. The heavier arrow makes the bow just that much quieter and it doesn't cost you anything in trajectory.

For critters further thanthat, remember... tournament rules do not apply in the hunting woods.A smart hunter will have a good range finder and USE it. He'll know the distance exactly, before he ever draws the bow. When the exact yardage is known, it doesn't much matter how flatthe arrow's trajectoryis.

And the heavier arrow retains more energy downrange for better penetration potential. (Around here, it's entirely possible to get a shot on a 500 pound Russian strain wild boar while deer hunting, so having some extra penetration potential is a good thing!) So, for hunting, I againsay might as well go with the Terminator Selects.

I've also found the Terminator Selects much higher quality than any all-carbon arrow in the same price range. I really, really like them.
