In case you haven't seen this (Handling aggro snakes)

YouTube - Handling an Aggressive Snake

Is the poster a member here? What he showed in this video WORKED on my problem retic :)

He's a member on http://www.redtailboas.com/forum/ he knows his stuff....I watched/read most of his info on that site when I was planning to breed boas...

His techniques Do work to.

This technique is called "dabbing". You can use a pillowcase or snakebag instead of your hand as well. My zookeeper bf always has to dab any large snakes before he handles them, regardless of their temperament.
