I've been following this thread about covering and the weights, etc. I
have data from somewhere in the past that says the 1 micron stuff weighed
.0008 gms/in-2. That would imply that .6 micron covering would weigh
.0008*.6=.00048. That seems like a big difference.
 
Then I was thinking that a typical EZB is about 75 in-2 on the outside and
the difference is 75 * (.0008-.00048) = .024 gms. Is that killer
penalty? The sketch I saw of Kang's EZB has the model at .374 gms for the model.
 
I've seen Kang's models and yeah they are a work of art at that
weight...but the .024 grams seems like humidity on the wings can be more than that,
or even the tag ends of the rubber knot.
 
And, how do you guys build that light? I am impressed.

Agree, I've always just weighed a sizeable piece of what I have. I use
others' reports to decide what to buy in the first place. Never been
disappointed. The color(s) alone usually indicate what to expect. However, a
couple others here have reported big swings in weight, esp. PPP film.
