I am a non resident and have 3 points for deer. Which one of these units would you recommend 40, 68 and 70 third seasons and why? I know I am still a year or two away but just want to get a head start. What is public access on these units like? I really want to chase at least 170 inch with the potential of bigger. Or if there are any other units I might be looking over that I could draw and have good success. Thanks
