I'll handle the pythons a bit except I rarely have the royal out. I let Sniper ride for the most part. If he sheds again, I may get him out one more time.
The Bredli, Kevin, is still pretty busy and growing. I'll feed him through the winter plus he's a bit flighty so I have to work with him.
Back to Sniper though. He's HEAVY!
Boas, depending on the locale, are a great species for people that want a large, impressive snake tends to be placid and relatively predictable. They don't break the feeding bank like retics or burms, but do carry length and size with some arboreal tendencies to up their display value.
I wish I could get a photo to show Sniper's size like I was able to with the coastal.
