I have to say that Annah really nailed it for advice.
From what I can tell, I'd stick with that first wig. I would still like to see what it looks like from a further distance. You certainly look the most convincing and natural in the first one.
If it makes you feel any better, I had hair down to my mid back by the first year out of highschool. I decided to cut it all off because I need a "change'. One of the worst ideas EVER! So, I know the pain of trying to grow hair out.
