"So I have an oportunity..... but should I?"
Honestly, no, I think you have a fine compliment of large snakes. I've watched you progress here and I like your enthusiasm.
I'm not sure you'll be in this 10 years from now though. I've mentioned this before and I'll say it again. You need to slow down and enjoy what you have. Focus on proper care for the long haul and put your energies into the habitats.
No doubt you've schooled up in the last year, but don't turn into one of those folks that hoard, becoming totally engrossed and then end up completely out of the hobby. I've seen it happen a lot.
There are very, very few long time big snake keepers out there. Reasons for it are fairly clear.
Some of the big name retic breeders from a few years back are completely out of the hobby after making a big splash for a short period of time. Other than bcr229, I see very few folks here that have had big snakes for long periods. Granted some people may just not be posting on the boards, I have also seen plenty that are totally out of the hobby.
You asked so I'm giving you my honest opinion. Pass on this and concentrate your efforts on what you have.
