I too prefer the look of the English and in the long term future I may have a couple, after my kids are grown lol
For now, I like my French as far as time on grooming goes and such...
They would be FINE in IL. My best friend lives there in Rockford and Angoras LOVE winter temps, it gets about as hot here in RI as it does where you are.
Check out my website if you haven't already, just to see more pics of my "babies" lol
I drove out to PA from RI to get them, I wanted them reallllllly badly! But now I am the only French Angora breeder in New England.
