Help me make a list of snakes!

[geko]

Sorry if this thread doesnt belong here but since its not a certain type of snake im talking about i figured it would go here.

I can have 6 snakes and the onlything i request is they stay under 6'

My current list consist of:

1 - brazilian rainbow boa
1 - ball python
1 - jungle carpet python
1 - tangerine honduran milk
1 - california king

That leaves me with the choice of one more snake and im looking for suggestions. If you choose a snake i should get then please explain why i would want it so i can understand why its a nice snake to add to my collection.
