sorry for your loss! Loosing a dog after such a long time is like loosing a close person.
I hope you can find some distraction in our hobby.
Regarding the crosses I can recommend you Killing Fields. I love the strain as it has many nice phenos and it is an interesting strain. It is quite a trippy one though.
I remember @Sunnyvale grew the Blackberry, just as Goodfellow said. From @Sunnyvale I had two crosses Jack Candy x Jalisco Jaze and G39 x Jalisco Jaze. I haven't grown any of the parents yet, but his crosses were really nice! I should make a report actually. The NAW guys do great work and Sunnyvale found a nice partner in Jalisco Jaze I guess.
I think Apollo x Green Manalishi would be an awsome cross too though.
Wish you a nice grow.
