Talking of volume, I think 5*5 at high % of orm is crazy high for squat. I've tried it and it took too long/ I got too ragged in the latter sets. Much prefer 3*5.
+1, always been absolutely killed by 3x5. And probably had the best gains from drop sets - dropping 5%~ off the second then 3rd set. Means each working set is properly intense.
