When you say commercial, do you mean private sales? Or donating to a dispensary? If you just want the biggest buds with the most weight and still have a great high... grow Critical HOG. It's a mix of Tennessee HOG and Critical Mass.
Tennessee HOG is a strain that a lot of us grew in Tennessee before coming to SoCal. It's literally one of the best strains my state has ever produced. It might have even won an Amsterdam Cannabis Cup one year. You lose a little face-punch off the high of the HOG, but you get some huge yields with the CM genetics.
Now if you are talking about a dispensary:
I'm in SoCal and the best commercial strains are anything other people don't like growing and no one has. Blueberry's, Afghani's, Haze's, *Real* OGs, and basically any really good and fruity sativa. It's illegal to grow outdoors here, so sativas are pretty hard to come by in a lot of dispensaries.
Economics. Supply and demand. If you are the only one growing a strain and you grow half-way decently... you can get more for less weight and basically come out even. Then you can grow what you like smoking and still be able to get rid of the bulk.
