Humm! I would say wait a few more weeks and see what Martin has in there 2013 line up. Not sure what type of archery you will be doing but the prowler is an ATA 30 inch. Great bow for tree stands and or hunting blinds, my experience is a shorter ATA is not that forgiving. If you looking at 3D and spot type hunting, you may want to see what Martin has in the 2013 line up that ATA is around 32-33. Also remember that allot of the archery suppliers will have to move the 2012's out for the 2013 bows, you may find a great deal on a 2012. I would look at a 70# and turn down a turn or two and that should give you around 65# and you can alway's go up in lbs when you get your set up spot on. Hope thing work out.
