What Type Of Carpet Python?

[89Bronco]

I am in the process of getting two carpet pythons. Both are 5ft. Male and Female. The female according to the guy I am getting them from says she is a red phase coastal. Now he says the male is an Jungle/Diamond mix. I am so excited to get these guys! They are eating frozen rats already. I am not to familiar with the differences between the Coastal, Jungle, and the Irian Jaya. I know that they are different in sizes once full grown but am not sure how to tell them apart. I am hoping you guys can help me with that. This is also my first post on here! I am Ken and live in central Va. I have had ball pythons in the past when I was like 13 but had to give them away according to some stuff going on. I have really been missing my snakes so I am now getting back into them. Just as pets. Been looking around and I am really liking the Carpets! Thanks for any help guys!
