Thanks Haukur and everyone,
 
I feel more knowledgeable now about R's.  So generally every R is rolled and the voicing can vary depending on the word.
 
Haukur, thank you for the Draumbr example.  It helped and actually made me realize that my "ormpr" was a "ormbr" after analyzing it.  It seems a good time now that im more comfortable with my R's, to move onto lesson three!  =)
 
Thanks people.
