i want to buy a chi flat iron but can`t decide between the regular chi 1" the turbo 2" or the "big chi" which is a 2" i have long curly hair and need a good straightner, also i heard that it dosent matter wether u use a 1 inch or a 2 inch it will straighten at the same rate, is this true? so which one should i get? thanks so much! also it would help if u`ve used them before
