+1 for Redwing - start with a program that has more horsepower than you need and you can grow into.  Go to the field level if you wish - been there, done that.  We are at the crop level and I can still tell you from other GPS maps etc... which ones are winners and which ones are losers, I don't need my accounting to tell me that.  It takes too much time and energy to break it by field when you don't make $/agronomic knee jerk decisions based on that field.  What if that field get's hit with hail for 3 years in the row by happenstance... doesn't mean you walk away from it.  It's all part of the average, make sure the average is in the green.
