Greg, I have seen this kit built up basically out of the box and it "looks" like the Arizona. My attention to detail and level of detail I am willing to build to is taking it to a completely different level. As far a fitting together most Trumpeter kits seem to build up fairly well it seems. As for the KA set with the wood decks, that will have to be up to you. My opinion on the wood deck thing is that they are placing a thin piece of wood over what should be the deck level. If that wood sheet is 1/64th inch thick, it adds 3 scale inches to the deck and if you look closely you can see a lot of things that have to be changed. I don't really know much about the KA set, but I am sure that it will be done to enhance the basic out of box kit. I chose to paint the decks so as to get the exact look I want. As I posted I bought the Eduard Big Ed set and I believe it will work fairly well for me, at least what I end up choosing to use.
There is a book that is considered the "Bible" for the Arizona that for a long while was much sought after, hard to find and really expensive if you did find a copy for sale.

I also found a lot of my references as photos online. I think there is a ship building forum that another guy was doing similar to what I was doing on this, but he stalled out years ago. Have not been back there in many moons. I did find the link to the actual blueprints for the Arizona from there. Downloaded them and then cleaned them up in a major way and reset them so they could be printed out in 1/200 scale if you so chose to do it. I could e-mail a copy of those to you if you are interested.
Anyway, to build the model it is your choice as to what you decide to do. Of all the people that would ever look at it, maybe 1 in a thousand might know some of the things that I found out from research. I think it is a better kit than the 1/350 kit by a long shot, but it is something that can and should be detailed up to give the best tribute to the original ship in Pearl Harbor.
