Much easier to breed in tufts than it is to breed out any tail, partial or full... in fact, I have a pair of bantams that are completely and totally rumpless, yet their offspring that inherited the hens tufts are all tailed... every single one, and not partials, full tails... didn't expect that at all...
So far though, with Apollo in my lf pen, he is throwing great tufts to his offspring... and 100% rumpless so far...
Personally, I would be a lot more picky about the quality of the cock than the quality of the pullets... to improve, you're either going to need multiple pens, or linebreed back to an excellent specimen... easier to do that with the cock than a pullet... jmo...
