Thanks Marty and Gary:

Do either of you see any serious potential problems using (in
competition) the rubber that I had to lightly tear apart?

I will see if I can detect (via microscope) any differences between
the edges of the clean cut rubber compared to the "torn" rubber. If
so I will test wind specimens of the two different types on our
torque meter to see if they vary significantly with regard to their
break points in terms of max winds and highest torque.

I stripped about twenty feet of good rubber, which we could always
use for fun flies, but hope it is still good for contests. Half of
this batch of good rubber remains in unstripped condition.

Thanks,

Calgoddard
