I know it will kill any deer I shoot with it.I just wanted more speed for 3d, but to be honest,I don't shoot that much 3d anymore.I didn't shoot a single tournament this past summer.Bass fishing got in the way.That's it.Once I put my new string on, there will be no more mention of a "slow bow".All of you are right.It is plenty enough for hunting.It is a quiet,beautiful, and accurate bow.I much prefer carrying this bow into the woods than my BW.The physical weight is so much less that it is unbelievable.I shot that BW for years and thought that I never could shoot a longbow well so I just kept with what worked.I finally sold my BW and have no choice but to make this bow work.I'm not quite as accurate with it yet as my recurve but it's coming.Maybe in time I can get a faster longbow like an ACS if I need to but for now I'm happy with what I have.Thanks.
