I recently purchased an Italeri 1/720 scale USS Ronald Reagan aircraft carrier, and for the life of me I don't know why they did not scale it to standard 1/700.  Anyway I am wanting to add some photoetch rails and details to this along with a full compliment of aircraft.  Has anyone used 1/700 scale photoetch on ships in 1/720 scale?  I am worried about the scale difference.  Any advice would be helpful.

Thanks
