After owning a MQ-1 , a Ultra 2 , and an LX (and shooting tons of friend's bows)over the last 7 years ........I don't think the valley is that bad for a Mathews at all. My Ultra 2 would rip your arm off if you crept much......true be told !!
I felt the draw on the Outback was comparable to the LX and when letting down it had plenty of room for creep on 80 % to me ! There are plenty of other bows that I would be more worried about creeping with/or letting down with........including some of the favorites around here !!
