Wear gloves. I haven't had a problem being bitten while handling. My problem was being bitten during water changes. As a result, I've made it my habit to wear gloves whenever I reach into his enclosure. I think yours will calm down with age and continued handling. I like nitrile gloves for handling. They're more dexterous than work gloves and allow for more sensitive handling.
As for how to remove a wrapped snake, the one time my Children's wrapped me, I just waited for him to figure it out. Personally, I found the bite only mildly irritating and, frankly, a bit humorous. I can imagine that I would feed differently if it kept happening, however.
I'm so glad to hear the Antaresia army has a new recruit. Don't be shy. Post pics. Start a progression thread. I'd love to hear all about your little monster's adventures.
