Unit 2 is one of the best Colorado has to offer. Do you have at least 20 preference points? You left out a few details like if you want an OTC, draw unit, DIY, outfitted, time of year, drop camp or bivy? Once you fine tune that go to the Colorado DOW website, it has tons of stats on points needed to draw an area, herd density, hunter density and success rates for those areas. Give that a try, it'll be a better starting point for you.
