Back rounding can come from a number of form flaws, including head positioning, which is generally number one. If you lead the deadlift with the head, and focus on standing up, it will help a lot with the back rounding. Don't focus on lifting or leg pressing the weight off the ground.
A lot of lifters start the lift and they start to look down. The body follows the head. When the eyes/head go down the hips come up, and your back rounds too much.
Start the deadlift by moving your head up, next focus on standing up with the bar in your hands instead of pulling it, and finally thrust your hips forward during lockout, like you were having sex with the bar.
As far as rack deads, they can help, but for some they don't do much. I might suggest RDLs instead. Check out the Rippetoe video on the site. I think the RDL may be more beneficial for you right now. It will help you focus on that lower back and keeping it tight, and will help build lockout strength.
You certainly could add rack deads to this equation.High pulls are also a good choice.
Ill focus on keeping my head up next time. Not sure if I do now but it makes sense to keep it up.
I do straight leg dead lifts on monday, Regular dead lifts on friday. So tomorrow when I do straight leg, ill make it a point to look up before lifting the bar.
