U shape haircut for man

hi everybody.
First sorry about my poor english, i am brazilian.
I am a 28 yr old man and I have long hair 5 inches below my sholders with layered bangs in front (smallest part 1 inch under my chin) and straigth in back with short body wave. My stylist ask me to cut it rounded in back in U shape with layered bangs starting on my chin. My bangs are in this way : http://hairstyles.hairboutique.com/tcgallery/tc0019.jpg

but my hair is not so long, i dont know if the word bangs sounds right to what i am trying to say. The front part of my hair is 1 inches under my chin, and the rest is cut in diagonal until my sholders, but in back is with a straight cut. I like the idea to cut it rounded in U shape in back, but i would like to know the opinion of others.

I think my stylist is talking of something like this:

(this is not my hair, is a haircut that i found on the web)
My hair is almost in the same size of the picture that i' ve posted above, my other doubt is if i cut a soft U shape like this picture below or a more pronounced U shape in back.

What do you think about it? Have anybody pictures with this style or other style that i can use?
