I'd recommend unicolor to start. Nice ones aren't too costly. They grow large, do well kept in the 70's to low 80's, and are generally mild-mannered super nice snakes. It's enjoyable to raise any Drymarchon from hatchling to adult, observing changes which occur. When you're comfortable with these, nice red-throat Eastern indigos are still the most beautiful Drymarchon. Photos are hatchling Eastern and unicolor from past years.
