It would definitely look better with some tires other than stockers under it.
Looks like it will be a fun rig though!
I don't have any personal experience with the F-150 coils, but from what I've heard on the web, as well as from a friend who has them, is that the ride is a bit stiffer, but they give you lift. I wouldn't care for springs that are stiffer, for wheeling, but if you just want to get the front end up, then they'll do fine.
