Different bob cuts

Hi Debi,There are gobs of bobs here but most are one length and I am really looking for a bob with like graduated layering in it where the layers start at the front and get longer as they go to the back. My hair is pretty thick and fairly course so these layers would hold down the bushiness and provide more movement. I appreciate your response and if you have any other suggestions please let me know.Thanks.> Check out this web site:> http://www.aluna.com/worship_bobs.html

I want to go for a bob and I have heard of many different kinds and I was wondering what the difference is in like graduated bobs, layered bobs, wedge cuts, feathered bobs, and elevated bobs. I would like to get explanations and pictures of these. If anyone can help me please let me know because I want to get a great bob cut for versatility and ease of styling but I do not know which one to go with.
