Private is pretty good, you get XP really fast and can buy better training then.
Well I was on my way to Yagoton but I had to pass through Brooksville, the place has been completly over run, it seems every building has 10 + zombies in it, and they burst into the church I was sleeping in and killed me so i'll start making my way back to Yagoton once I get revived which might take a while beause they've taken the Necrotech buildings.
