i had hoped for improvments in SR2 but havent found any, my suggestion would be to turn down dynamics in animations ,with shorter hair such as yours it seems to work pretty well, i would suspect root stiffness falloff is dif on one section than the other making the humps shown, this collision prob i havent seen before ...are you using a hair cap with this? hair looks good cept for those things you mentioned, cute figure...

:O)

Y'all have a great day.
