Resistance is futile 
I’m still a low level chucker - full disclosure 
You have a solid toolbox already 
So now it’s just about decisions & planning & observations & time & space. Easy. 
Growing weed is easy, but commitment is not. So, onward through the fog. 
Defining goals & simplifying will make it all a little bit easier.
4/4 is promising but 99/100 would be more confidently “isolated” but without knowing what mechanism in the plant & it’s dynamics(as a community) we can’t really say what’s going on with the 'blood.
I’d start with one or two goals in making a hybrid or exploring or inbreeding… like Plant A tastes great but it’s buds are too small & Plant B tastes ok but has massive yields, then A+B=AB with some variation. If both parents are unstabilized polyhybrids then buckle up for surprises.
Or maybe you want to add CBD to something… 
The “KISS” principle (keep it simple, stupid) really helps orient me with this stuff.
