So comments like mine get old and then you go on to say you basically do the same thing?
Yes, I go both routes depending on plot size. I just don't think it necessitates bashing someone over their new purchase..
Regarding your question on seed blends, it really depends on what you have to work with. Personally, I 1) disc 2) spread larger cereal seeds 3) cultipack 4) spread smaller clover/brassica seed then 5) cultipack again. In that order.
If you have access to a drill, I would probably just mix everything together and go shallow on the drill, 1/4" depth so you're not burying clover/brassicas too deep. If dragging a harrow or fence, I'd drag over larger seed and seed smaller ones after that as you've suggested.
If your seed is already premixed, I'd probably drag/harrow first, then spread seed, then pack in.. And hope it rains soon!
