I have some of my C99 Punch line f2 soaking to work on a bx, but I am probably going to use frozen male pollen as the P1 donor rather than go back to the Punch cut. The f2 generation are looking like a nice combination of cinderella genes so I don't see a problem going back toward the male side of the line. I see a great deal of the punch looking plants coming out even in the Metal side of the line.
