Which CHI should I get?

[prettybabi11492]

I have wavy hair that's kind of naturally straight but kind of wavy. It takes about five minutes to straighten my hair. Should the standard be okay, or should I opt for something else?

the standard should work fine. I brought it when i was in the US as my GHD's wouldnt work over there and even in the Florida humidity it worked great
