Well, let's see what I can share here. One note..I'm only 7 months into this, so other than talking about m y own rabbits, it's all word of mouth from either my breeder, or others I've talked to about rabbits. (and I do a LOT of online research)
The angoras will all (except the German) shed eventually. Many of the breeders of the French angora have bred for a 3month shed (which is what happens in France..although the commercial breeders there use a depilatory to get them to shed all at once). The English tend to hold their wool longer (probably because of the lack of guard hairs?) English will grow lovely long luscious hair...but you need to groom them more often the longer you let it grow. Many breeders just shear them every X number of months. Biggest problem seems to be shearing AFTER they've started shedding..you end up cutting off the new growth along wtih the old.
Many of the English breeders I've talked to use a blower to groom, instead of brushing. It's done at least 2 times a week, and completely detangles (also blows out any dander). In a pinch, you can use a hair dryer (no heat...just fan). Others us a comb and slicker brush instead of blowers. The English require a LOT of grooming compared to the French and Jersey Woolies (JW are decendents of the French Angora)
Jersy Woolies shed. Trufflebee goes about 3.5 months. He's easy to pluck. I just put him on my lap and start pulling the stuff that sticks out. Not the guard hairs...but the fluffy stuff. When I'm done, he looks skinny and pathetic
I do groom him, but not very often. Feet and tummy area are most liable to matt. (and behind the ears if they start scratching)
My girls are French/english crosses bred specifically (over the years) for fiber, to not mat, and to shed every 3 months (moult). There are two ways to tell if they're ready to pluck. 1) the cage wire starts to get covered with wool; or 2)when you groom them, the brush is full every time you comb through.
now me...I groom my girls once a week, not because they get matted, but because if I don't, they get REALLY wild and forget the "me master, you bunny" thing. and "being upside down is FUN!!!" goes RIGHT out of their little brains.
JW wool is generally a little coarser than the Angoras, but not by much. It spins up nicely...you just don't get as much per plucking.
