Just finished guiding for moose last week.
I got to watch a couple of moose get shot with compounds. Hit them below center, height wise, tuck it as close to the leg crease as you can from as close as you can get. A hand width behind there will work wonderfully so don't get too caught up with exactly in the crease, might be better actually as it will buy you a little room away from the shoulder. If you miss, miss low. If you are not used to judging distance on moose, watch horses for a couple of days if you can, black ones in some cover. It helps as they are decieving. A direct hit on a rib with one of those replaceable blade, non cut on contact broadheads will lead to a long frustrating track job. 1/4 inch either way and the arrow goes right through. Your set up sounds awesome and will work great. Good luck, last week was one of the most fun weeks in the bush that I have experienced. Lots of moose up close and personal.
Our Trad guy had a moose within 20 yards but held up in cover until after dark. We were all pulling for him. I am wishing that I had drawn a tag....they are made for trad gear.
