AK-47,purps or blueberry?

Im looking for the strongest couch lock stone.
Ive already got white widow ordered.
Any other recommendations are welcome.
I'm looking for A+ smoke.
With all these strains its quite complicated.
In Amsterdam,i really liked the white widow and Amnesia.
It will be an indoor grow.
Space won't be a real issue.
I can handle the smell aslong as it isn't rediculous smelly like skunk.
(Daaaaaaamn,they smell up the whole appartement!!)
Alright,so i'm looking for an extremely potent couchlock stone.A strain that will knock me out on my ass.
Ak-47,purps or blueberry?
Ive been hearing very good things about white rhino and that for a"knock me off my ass",white rhino is the way to go.
Is this true?
Any other recommendations?

sensi star northern lights, hash plant, black domina to name just a few. preferably the original strains if you can get them.
