I can't really speak to having a short 27" draw length having a 27.5" DL and all, but season before last after I separated by shoulder I shot a ~420 gr. arrow tipped with a poke on impact 3 blade out of a 62# bow and got full penetration on a moose. I've shot a $#!+ load of game with a similar arrow at 70# and a 2" mechanical and virtually all pass-through's. Don't let the internet get to you - the decision isn't that hard. I'd look at an Axis or FMJ in the .300"-.340" deflection and completely strip the notion of Grizzly Sticks from your mind.
