DL form

I decided to switch back over to Sumo for DL. I am gonna put my stance in farther. I think I can have better form as long as i can keep my back from curving out (not keeping it strait lol).
 
Got any ideas how I can do this? I figure putting my stance closer then I normally do on Sumo will allow me to get my butt down....I also heard putting ur shoulders back will help also with head up.
 
I figured that I use too much back on conventional and can't get my butt down low enough to use a suit.
 
 
Any ideas helpful.

sorry bro this is lost on me, I didn't know there were different typs of form used in dl

yeah, sumo is feet wide (like a power squat), and conventional is bsically shoulder width...either way is good depending on ur body type and strengths.
