Not really, I would just use Trifecta stats + Primary + CDR, keep 3/5 attributes.
You can reroll the stats you don't need, and if you find a Primary + CDR ring, just trash it; everything else will have a stat rerollable to one of your rings.
Otherwise, you can use the tigher version "Keep 4/5 stats", but you would miss out on some rerollable rings (i.e. Ring with Primary/AS/CHC/X would be trashed unless X was CDR).
