I think you will be happy with either. My only suggestion would be to consider a female. I know you say this will be your only one....... But many people before you have said the same thing only to get bit by the BP bug. And decide later that they want another one and also want to try breeding. Well a female is going to take at least two years to get to a good breeding size. So when you finally come over to the dark side..... And you will..... You will already have a girl that is ready to go...
