Input for new autoflower crossing strains

I have been working on a breeding trial with the few strains that I have -- with good success thus far. Meaning, I made feminized pollen -- pollinated two plants that appear to have abundant enlarged calyxes -- should have a ton of seeds. Of course, I will not know how successful things are until I actually grow from these seeds. But, let's assume all goes well -- I will be ready to try some new genetics.

My questions is: What autoflower strains would YOU choose to cross(or have crossed) and why?

I want to choose a few strains...picking ONE strain to herm and collect pollen -- pollinating 3 other strains from this herm. Also -- If you have an opinion on which strain should be the herm(pollen donator), please let me know.

Jungle Wreck Seedsman Seeds (Genetic:Columbian indica) and Chronic Lights (crossing: Chronic x Northern Lights) our Pure Kush (genetic: Hindu Kush) Original Sensible. And the I want see what happening,any way selection it's a long 2-5 generation it's a minimum 1 year. I can share some Chronic Lights,because in last year I grow it and get couple hundred's grams of seeds,but I think there are 75% chronic lights it's a not first generation and not so strong.
