If your snake doesn't have a lot more growing to do, you could try the realistic, tortoise shell hide.
This retic was pushing 9 feet, although he was very lean, and still fit into this hide.
My thicker, but shorter boa also fits well.
Just a thought, but I'm sure your animal will exceed the size of what I had.
I miss this guy in certain ways after I post up his photos.
If you like the look of this and think your snake will fit, it might be worth a shot.
Good luck with whatever you do.
