Howdy @MikeyMeteor, I’m just sort of catching up in the thread here. I think you can go at it choosing a male where it’s traits and qualities can be dominated by the Sour Diesel in the more immediate progeny or by choosing a male where it’s traits show more influence in the immediate progeny.
That said, I notice you mentioned earlier wanting a Jamaican with under 14 weeks flowering and thought to mention something that I just learned recently. '79 Christmas Bud comes from Jamaican import found in Port Charlotte as referenced below:
Also, I think males from some of DJ Short’s Blueberry work will pair well with Sour Diesel. I think a 12-14 week Destroyer would pair really well with Sour Diesel as well. Neat project you’ve got going. Wishing you great success. Many blessings and much love
