My first brisket with Q-View

So tomorrow will be my second smoke on my new UDS that a friend built for me :-)

So I am doing a 7 pound brisket also two racks of spare ribs also some potatoes and a couple fattys! its gonna be a fun day. 

So here is the brisket

I scoured the fat cap

Slathered in mustard

Then I put Jeff's rib rub that I made to my taste on it.

then wrapped in plastic and put in the fridge over night! so I made a beef broth, V8 and Rub do I inject tomorrow? 

Also I always use hickory and I like that alot. but should I use mesquite? and will my ribs and fattys still taste good?

thanks for any help.
