I have a couple of questions that I would greatly appreciate the answers to. This is my first time getting a hair system, and I'm thinking about using the following specs:

Full Cap
All French Lace
hair color: black
hair style: freestyle
curl & wave: straight

In reference to the 2 attached photos in this post:
1) Is the density 65%, 70%, or 75%?
2) Even though 6" hair length is included with the order, I prefer not to go into the haircutting place with too long of hair. Therefore, based on these photos, should I request 5" Hair Length or a different length?
3) After I make my template, I am planning to label "front" and "back" on my template. Since I have mentioned hair style: freestyle, do I still need to mark Arrows on the Template?

Sorry for all the questions and I really appreciate all of your help!
