You will want to maintain Fracture *constantly*, even above Butcher's Block, since, as soon as you've set up a decent enmity cushion, you don't really need *more* threat. At that point, it's all about damage.
My default rotation is BB Combo>SE Combo>Fracture>BB Combo>SE Combo: you'll maintain 100% uptime on Fracture while generating all of the enmity you'll ever need (unless you're running with a PAL in Shield Oath spamming Halone, at which point your only hope of keeping threat off of him is just spamming the BB combo without rest).
As for opening, I start with Tomahawk and move into the previously indicated rotation. Tomahawk's 2x threat mod coupled with the Defiance multiplier gives you all the time you need to get into the end of your first BB combo, which will give you *more* than enough threat. More than one BB combo back to back is overkill unless you're undergeared and dealing with a BRD that is amazing at DPS but doesn't know how to use his enmity management skills.
