I agree with your thoughts on the DU. Reading into your post, can I assume that you would focus on OL and slow lifts for power/strength development, gymnastics for skill development, and low-skill movements for metcon?
Yeah, more or less.
Focus on strength/power with the high skill movements such as C&J/snatch/muscle ups/other gymnastics stuff. Metcon ONLY with low skill lifts. Don't want to distort any technique gains made especially with the novices for the lifts.
Focus on getting powerful/strong and really fast, then maybe 3-4 months before competition work on increasing metabolic capacity to the max.
And unfortunately, no GOMAD for me. I was drinking lots more milk, but it was giving me acne as I am allergic to something in it (I think the casin possibly?). So I just dropped it.
