you'll obviously wind up with a sativa ... potent parents, and the resulting 'hybrid vigor', you should have a powerful sativa F1 ... not much doubt about that ... but, expect a long flowering period, as I believe both of those strains are probably 12-14 weeks in flower ... the variances will appear in the F2 generation, probably ... since there is some similarity in those two strains, you may be surprised with decent stability ... ya never know for sure, till ya grow 'em out ... :smokin:
