Fifty pounds is more than enough to kill a deer sized animal , switch to a heavier arrow .
Why increase your risk of damage to yourself if your current set up is already competant for what you hunt ? I can't count the number of guys I've seen who have had to permanently retire from bowhunting because of shoulder damage from shooting high poundage bows , and all over some false sense of being "manly" or a useless quest for one more foot per second that won't even matter. If it ain't broke don't fix it .
