I never saw Hanger 9 mentioned either. The only difference between H-9 and Tower is the old Mono vs Ultra debate. They both send out ARFs with wrinkles and bubbles, it's the nature of the beast and you just have to live with it. I do find Ultra easier to work with and it tightens up with far less trouble and work. I have assembled ARFs for people over the years that I think were covered with tacky shelf paper, some of these were easier to shrink up then others.
If you are going to buy ARFs you will usually have bubbles and wrinkles when you open the box, makes no differnece who is selling the plane.
