Are you trying to ask what RC cannabinoid would feel the most like a low dose of THC with a higher dose of CBD? If so low dose AB-Fubinaca is actually one of the better candidates for that, though it's very potent so anything but a lower end dose will feel pretty damn strong. It's more potent than JWH-018 for instance.
^ I agree. I have a bunch of cannatonic. Can be pretty rare and hard to find. So when I find it, I stock up. Cannatonic and harlequin are both strains with high cbd and low tch. There is also a strain called ac/dc. Pretty much all cbd.
