It's pretty typical when flying under a bubble canopy to add seat
padding until your head is right at the canopy crown, or at least as
close as comfortable. Glider pilots do that all the time to improve
visibility over the nose and downwards over the cockpit rail.
Taildragger pilots tend to do that to improve visibility during takeoff
and landing.

As much as I'm not a particular fan of the Harmon airplanes, I can't
say I'd do much different. I think that a good static test to a
_design_ limit of 6g should give you enough deflection data to
extrapolate the stresses above that to a reasonable degree of
confidence, and should leave you a flyable aircraft besides. I don't
think I'd do a static test to ultimate limit unless I was doing
something unorthodox or was expecting to manufacture finished aircraft.

Thanks, and best regards to all
