Thanks to all for the feedback, really appreciate it. I'll drop the weight a bit and start ensuring my hips stay down during the first pull. I tried pushing my hips back into the squat today during my snatches and it felt fecking horrible, my upper body leant way too far forward making it difficult to catch the bar. Oh well I guess more practice is needed!
Cheers for the recommendation on the article mate, just read the article, great piece of advice, I'll start lifting facing in the opposite direction. Should help proprioreception a bit!
