I smoke mostly Lebanese Red, a landrace strain. I started breeding some CBD x THC strains, got ahold of some Lebanese beans, and decided that there was no need to re-invent the wheel. Nice balance of CBD and THC. Some THC is better than no THC in my experience. Some CBD is also better than no CBD in my experience. CBD strains that I have bought at the local stores here in Oregon are all over the map in regard to CBD and THC content. Even for the same strain from the same grower. Similarly the same seed runs of high CBD hemp strains vary a lot. CBD is fickle and inconsistent in Cannabis, even in high CBD hemp strains.
I have lots of high CBD strains, some I grew and some I bought. Sour Tsunami, Therapy, Frank's Gift, Charlotte's Web, Canna Tsu, ACDC, Harle-Tsu, Harlequin, Ringo's Gift, etc etc. Some are 50/50 CBD/THC, some are almost all CBD and less than 0.5% THC. I also have pure CBD crystals that I get from Colorado. I use that infused in my own rendered hash oil for using with skin salves and the like. I use it on my hands, which have arthritis, and it works wonders. I also use it on my back and neck. THC in skin creams will not get you high, contrary to some beliefs. I also add CBD crystals to tone down hash oil that I make to smoke.
So far CBD is an inexact science, but the key to high CBD results in growing plants is either grow a lot of them and clone a plant that tests high in CBD, or grow like they do in Lebanon in large fields and mix the harvest so the cannabinoid results are evened out. Or buy pure CBD in crystal form.
