best wavy hair?? need it asap!!!

I did a consult today and she has a level 2N THICK bob, going to be fun!!!! I need to get 8 oz. of wavy hair. Her hair is a medium texture, and her wave pattern is between a soft wave and a medium wave, but not yet a spiral. (does this make sense?)
I've not done a lot of wavy installs, and I once ordered bohyme french refined and it was a dry frizzy mess!!! I want something that will keep its wave and not turn frizzy!!!
I've seen on ebonyline.com bohyme has a couple of different wave patterns and the soft wave looks pretty good, the french refined looks pretty curly to me.
I'm also considering virgin indian hair, not sure of any good suppliers though.
I've also heard some good things about wagmun primus.

Any suggestions would really help!!!!!!!!!!!!!

the cheapest I've seen so far
