I've never shot the Outback but I know Matthew's does make a high quality bow. I do own a Mighty Mite and love it. I've had my MM for three deer seasons now and just cannot come up with any valid reason to replace it. It's just a great shooting bow.
I shoot about a dozen arrows, almost everyday from June thru November and the just keeps working great.
Another thing to consider is that BowTech comes with a Winner's Choice string.
