Great points in here. Just to throw in my two cents I think that form is THE great constant in terms of things to work on. As your strength improves, this can highlight flaws in your form and imbalances in your muscles. Form is not a learn-once solution; it needs constant review and the strongest lifters will always have the best form FOR THEM. This will come from experimentation, mobility work, assistance exercises and lots of hard work. When you watch Vogelpohl squat 1175lbs with his feet wider than the monolift or Duffin pull 900lbs raw with a sumo stance, you are watching a thing of beauty; the ultimate in efficiency, technique and strength combined. Don't ever stop learning.
Don't call it a comeback
