I talked to a guy from the London area that said they could finish Jackflash and it's crosses, never tried it nor do I have the pictures. Sensi Star should work I think though as people in New York can finish it. When do you need them to be finished by?
Easy Shifer i'm from 52n South-East UK, i have Niravan's Papaya that finishes end of Sept. I'v also had A few others work good too. Sweet Tooth 3 and a Kush X Black Domina, and Easy Bud.
