Thanks for your feedback guys. I've been doing some research on the sumo deadlift online. Even though the SS book has been extremely helpful to me when it comes to learning good technique, it's the not the end all be all to me and I'm open to trying the sumo style. Maybe it'll feel better and be a safer way for me to lift. I don't have very long arms, so maybe that style would be easier for me? I'll give it a shot on my next deadlift session and report back. Sorry I didn't upload a video...didn't realize I deleted them all, but I'll definitely do that in the future.
As far as my chin being up, I've found that I have an easier time keeping my back straight if it's up more, but will try to keep it down while keeping a straight back.
