It has been my observation that JW bred to French, Satin, or English, really doesn’t help any of the breeds out. The differences between them, while subtle, are actually really succinct.
JW are meant and bred towards having a large presence of natural long guard hairs within their coats, per the standard. If your friend is a fiber person she probably won’t want this in her normal angora herd as the guard hairs can be tough to work with and ruin the finish halo of whatever she’s creating. Seriously, even the best JW wool can’t touch good French, English, or Giant wool.
JW are long haired genetically, same as the French or English. I have never witnessed a short hair (normal coat) pop out of any breedings from known 3 or 4 generation pedigreed JW. I have witnessed normal fur on out crossed JW bred back to ND, but that’s it. (ND can have naturally occurring “long hair” specimens, but those do not look like JW when mature, the coat is not woolen. It’s regular fur, just much longer than “normal”.)
Phenotype on the JW however, can mean that “long hair” per the genotype is only 1.5 inches on them (and some have even less!). ARBA Standard for JW: ideal wool 3 inches. Not all make that standard, despite genetically being long haired. My best of best wooled JW have never had wool longer than 4 inches, ever. Most stay within the 2-3 inch rule. Some lines the wool length is spot on equal to ear length.
JW have a different head set and body to them, imho, that totally gets ruined and doesn’t come back if any other breed, save a ND, gets crossed with them. This head set also negatively takes away from other breeds’ heads and shoulders when crossed with JW. I think your friend would end up with a cross that wouldn’t have either desired breeds’ body structure, and shorter than hoped for wool.
Color isn’t everything. But if it is, breed a tan pattern Satin Angora into your English. The tan lines are being worked with, so some of the hassle is already done.
