Any recommendations for strains or breeders?

I am looking for a breeder that has potent (high THC %) kush, or OG kush lineage genetics with dense flower pheno expression from seed. anyone have any personal experience with anything available through attitude?

I believe Karma genetics is a well respected breeder and has a nice variety of og crosses. I'm pretty sure you can get his work from Attitude. Also there's Archive seeds, he makes some good og crosses.
