Like the ol' Nike commercial said: Just Do It.
The two worst bites i ever had were an 11' retic that got me my second week working at Hogtown herps about 20 years ago. It bit me and pulled back, as did I, so the tooth that hooked into my thumb ripped it open to the bone for about 2", and required 12 stitches to close it up. It also severed the nerve on the side of the thumb, and to this day it still feels a little tingly. The other bite I got was a 14' burm about 3 years later at the same place. She nailed me when she missed a rabbit I was dancing in front of her, and didn't seem to realize she had me and not the bunny. I had a bottle of cinnamon oil nearby that I had heard was good to pour on a snake's mouth if they were locked onto you, but it turns out this snake only bit down harder. It eventually took three grown men and a tongue depresser to pry that serpent off me. It also hurt like heck when those teeth dug in about an inch into my hand, but this time me accbitshe and required no stitches at least. I'd hate to get nailed in the face. I had a lappet-faced vulture once nail me in the face during a falconry show I was in at Weeki Wachee, Florida. She had dropped her rat on the ground, and I bent down to pick it up and give it back to her, she evidently thought I was challenging her, so she bit me accross the nose. Blood ran down my face and was dripping off my chin, but I finished the show with the audience in stunned silence. Since they do have the most powerful beak of any raptor, I considered it a nice warning from the gal since she could have easily removed my nose from my face.
Yeah, just do it with handling that cribo. He might tag you, but it won't be all that bad. Most likely, he will be pretty cool and mellow right out after he gets to know you, which won't happen until you handle him some.
