Your set up is perfect for Moose, in fact, any north american animal. Perfect arrow flight and shot placement matter way more. I'm sure you knew that already. Get your two blades super sharp, hair popping sharp, and you're good to go. Good luck!
In regards to Fred, yeah he shoots 54-55lbs, but his draw length is long, gives him a larger power stroke. I can't recall his exact arrow weight, somewhere in the low 500g, but shoots it at 200 fps.
