I feel Im far enough in now to say with confidence that the "Greases Pieces" #2 reversal was pretty epic and quite the giver of very viable pollen.
Over the last year+ I've grown out a handful of GP's a few at a time looking for 2 standout plants to use for making fems freebies (one OGKB leaner and one GG4 leaner). After finding them & keeping cuts of each of them in the momma tent for months I was finally able to get to reversing GP#2 which is the very heavy GG4 leaner. She reversed so easily, and absolutely dumped massive amounts of viable feminized pollen:

Once collected I used it on GP#7 which is the OGKB leaner and realized within 48 hours of dusting it that the pollen was very potent and pistols were going dark brown and receeding. Loaded with feminized seeds and ready to go near black in the final weeks before harvest, here is GP#7 at about 6 weeks:

This is GP#2 at week 3 dusted with the same GP#2 reversal pollen to make some "Greases Pieces S1". This is 3 days after dusting it:

As you can see theres no doubt shes leaning hard to the GG side of the parentage. Greasy purple stripes in the stalks, lots of early frost, and that unmistakable terp profile that GG4 is known for. The leaf twist was real heavy in veg, but as it gets further into flower she begins to lose it.
There were ZERO intersexing issues in this entire project. I will have both the "Greases Pieces" Fems (mix of both parents) as well as some "S1's" to offer up. Since these are new batches, I'll need to have them tested before offering them up -even as freebies.
