I have one that is cottony - she is in my avatar with the long braid -
She is now SHORT cut lol - Way way easier
But I still have her long topknot
Cheri her sister is silky and very easy to keep up with unless wearing her nightie or something - I use Chris Christenson Ice on Ice for both of them - it really helps with tangles
good luck - cottony or silky we gotta love em right?
