For hair fittings I've always set the hair item up and adjusted it with the XYZ dials in Poser to raise it, lower it and expand it etc. I never used any of the "fits" for which ever character and it's worked for me. So don't panic if V3 or Aiko isn't on the list. I set the model in default pose mode [DM pose packages always comes with a default pose which is great for going back to start when something messes up and it won't affect your body  morphs] then I add the hair and select "Body" on the hair and then use the dials to adjust the hair onto the head. I use the Face camera and that way I can rotate around the head to make sure there isn't any scalp showing through. Then select set parent and find my figure on the list and click on the "Head" and "OK" and it's done. Probably done less than a minute.  The only problem I have had with it is when I've used packaged poses for the hair and some will adjust the hair to "Vickey" size if you were using it on Aiko or Mike etc. I've used Dixie hair on David and he came out looking yummy with the long tresses :) 

I don't have the latest Quarker hair so I'm thinking it can still be moved around like I normally fit different hair on models. There is talk of V4 being completely different than V3 as in none of the previous models clothing items are going to fit. That freaks me out considering how much money I've spent on V3 since 2004. ::Note to self...:: I gotta learn how to make my own stuff!

Some people on the Plat Club forum site at DAZ are posting their own images using the hair and they've managed to get it to fit V3, so I'm thinking it can be adjusted using the method I mentioned above. So far someone has posted an image that makes the hair appear cut in a very nice smooth bob like fashion...I wish Quarker's ad page had posted the various morphs for the hair instead of just showing the long stringy version. Well, since I know it can do many other hair styles....I might have to get it now...I have no will power whats so ever!!!
