If, as I hope, you read the comments on posts here, you'll know that Eira Kalil of Tiny Things pointed me in the direction of Wasabi Pills hair as another source of mesh hair. Thank you very much, Eira. There I found some lovely hair that gave me a serious 60s flashback.
I like its asymmetry and the stray unruly strands that add realism (the sort that we may wish we could do without when trying to arrange our hair in RL, but in SL are welcome refinements). Alas, one does have to be selective (though won't mesh hair that falls on the front of the torso intersect even stock avatars when they turn their heads?), but when it does work, it works beautifully.
(Note to self: antialiasing is your friend. sigh...)
