Ya I am with you on the males as far as your breeding goes sounds interesting hopefully you have luck on your strains good things take time specially with breeding....best of luck!
I would not breed will fem. seeds at all! Unless I found a pheno that was amazing and could not find in reg seeds....then I would stress test the pheno I found from gem seeds if it passed the test I would but don’t like to that’s just me though.
Ya found a resin male shown like 4 pistons but just reeks might have to pollen chuck see what the off spring looks like...if you find a resin male that throws like 1 piston would you breed with it?
