So I like to WoW cataclysm Gold do what I call ride the Viper which is only running Viper while on the steady shot part of our rotation this is very easy to do doesn't mess up our rotation because aspect of vipers off the global cooldown and causes zero mana swap into that looks like this
obviously you don't need to do this at 80% Mana more like around 15% to 20% mana,...
