i watched a lady spin yarn off her angora once. it was this big fat happy rabbit, practically purring in her lap as she groomed it. i don't know what it weighed but it was soooooooo soft! think of the nursery rhyme type big rabbits and you will get an idea. hers was a pet. she sold clothing she knitted out of rabbit fur.
they were all her pets and very very well cared for.
if you get one save all the loose fur you brush off daily. if you don't spin , trust me someone would love to have it!
your rabbit would want you to be happy. a female may be the best choice. good luck.
its called plucking, not shaving, btw.
