Eyeliner HT! How many grafts will I need?

[Slowmoe]

I plan on getting a HT around tax time 2014, so I've been trying to decide where i want my hairline and how many grafts it will take to get there.

Well I found the hairline that I like best by using eyeliner, and would like some opinions on how many graftds I will need to get there. Note: I did darken my temporal peaks some, i'm guessing 2-400 grafts total would be needed to fill in both.
