In a slight derail, Viper Bite is, at least at 75, equal to a normal swing. The damage is your normal main + offhand. I was getting 22 and 86 with Onion/X's, and I got 108 damage Viper Bites. On offhand criticals, I was getting 167, because the critical hits of X's knife were 145. Sneak Attack + Viper Bite was netting me 388 with no critical offhand, and were 445 with one. Without X's knife involved, they were a steady 22 normal and 273 with Sneak Attack.
This would debunk the dexterity mod that is currently on the wiki page for Viper Bite, and also, for what it's worth, make Shadowstitch the stronger of the two weaponskills once you're at the cap, because Shadowstitch carries a slight charisma modifier.
