Watch the Example 4 online guitar lesson by Brad Carlton from Guitar Lab: Boogie-Woogie

This example is the same as example 3 but the 1st voice is played on the second string instead of the third string. This will require a "split" between your middle and ring fingers when hybrid picking. Try playing the voices different ways. You can apply various arpeggio patterns to create different sounds and don't forget to try different rhythms.
