At the end of the day it's your guitar mate, do what you want with it. The below is what i had done with my TLA TH kit.
The whole point is to do something that appeals to you, or to who you are building it for. with the profiling though I'd be careful about getting too close to the nut, and remember to think of things like where your string trees and machine head washers and ferrules and such are going to end up.
Edit: FWIW 3 &4 are probably my 2 favs! Can't think why.....
