Shig:
Congrats on tube #1, and thanks for the update!
One way I have used to test some aspects of tube models is with a "test" tank, since I don't have access to a swimming pool. This is just an 8' diameter child's play pool which you can fill several inches with a garden hose. They are very cheap at this time of year, which is the end of the season. You can test balance, mark floatation level above surface, some stability, etc.
Also, looking at your inflation bag method, I'm wondering if you could cut time for inflation by using a nipple tube that pushes in just slightly on the flap check valve. Seems like if you move quickly, you won't lose much air and can quickly remove to finish by mouth tube inflation. Similar idea seems to work with my ODC 420.

25.4 ounces!!
I've updated the spread strap design to be cleaner and more integrated, and I've added a couple of grab handles to carry the thing.

And to celebrate I built my own "Ferrari" of tubes:

Unfortunately it is actually 1.4 ounces HEAVIER that the blue one! Oh well, what price cool unmistakable one-of-a-kind uniqueness?
Maybe I'll start drilling "lightening holes"?
I was going to try to maybe take it out on its maiden voyage tomorrow, but with the smoke from the fires blowing up the range, I think I'll stay home and work on finishing up the rest of the run I have going and maybe get some work done on some fins as well.
I'll probably try to get out again on Labor Day, perhaps...
