I'm certainly no male selection expert but Duke Diamond (Dominion Seed Company) talks about male selection in this Q&A I highly recommend.
Male Selection part starts @ 21:20 though I recommend watching both parts as Duke and Skunk VA are 2 of the best breeders in the community.
It goes deep into male selection, as it can get very technical. Fascinating information, in my opinion.
It makes me want to build a small male isolation chamber to grow out some pollen. There's always reversal methods, as well. Katsu Bluebird has a whole line with a reversed Pre98 Bubba Kush.
