welcome to the community rak,
you dare todo what most people dont want to try with and well done in able to make it sucessful and yes vids please!
If i was in your position i'd go in subelty to hemo and have a combat spec main. I just think that after a while the backstabber/mutilater would pull to much agro whilst hemo is buffing both rogues. I always think its a good idea when running all dps to have a char that you can always have agro on.
