RE: 55# Takes Yukon Moose!!!
OK Quick, riddle me this... Do you think that it is fine for someone to hunt with a 60# recurve? If your answer is yes, then your argument has no merit and you are simply flexing your muscles.
And bowhunting is a sissy sport. We sit in treestands designed for comfort and shoot bows that "eliminate hand shock". How much more sissified can you get than worrying about the recoil on a bow?
edit: If by "significant penetration" you mean a pass through, I did that 16 years ago with a 45# compound. Only non-pass through I have ever had was with my Mathews at 64#. Got stuck in the far shoulder. Think that today's bows aren't faster?
But don't let the facts get in the way of your opinion.
