Something I thought I might mention to you regarding your DLing. We have quite similar lifts although you probably squat slightly more. My dead too was really poor and I was finding it a really awkward feeling lift..like, it felt like I was stooping really low to get into the starting position..maybe just my proportions I don't know. I switched to sumo but srsly it makes a tiny difference to ROM, not like ultra wide tiny ROM sumo, basically just same width legs but I grip the bar between my legs rather than outside of it. 5 rep dead went up by about 20kg there and then, and that was on a bar with no knurling, probably get even more when on a proper bar. Might be worth giving it a go
