I found that Yumbolt is very similar to Black Domina. I have smoked Yumbolt in A'dam and it was one of my favorites. I noticed a similarity between it and the Black Domina that I have been growing since 95. Since then I have grown out the rest of my original BD seed and of the 2 that I have tried so far (still drying) the #8 female tastes exactly like the Yumbolt. It was one of the fastest also, harvested at 47 days. Very resinous, you have to take small tokes or risk coughing up a lung. I think Sag offers 20 seeds for 200 fl. and Sensi sells B.D. 15 seeds for 175 fl
