Fitting Material Choices

Looking at plans and am considering building another wood plane. Depending on the "version", experimental or ultralight, the wing attach fittings, etc. are spec'd as 1" X .090" for 4130 steel (experimental) or 3/4" X 3/16 for 2024-T4 aluminum (ultralight). I got looking at the material properties and weights of those materials and also looked at 7075-T6 aluminum specs. It seems I could get the same strength on the fittings using 3/4" X 1/8" 7075-T6 instead of 3/4" X 3/16" 2024-T4 alloy and save almost a pound total considering all of the fittings required on the plane. Is there something about 7075-T6 that would make it a bad choice for wing attach fittings and strut wire fittings where bolts and cable thimbles would be passing through drilled holes? A few of the fitting "straps" would need slight joggles and a few need slight bends, but there appears to be enough room to use a generous enough bend radius even with the 7075-T6.

It was either Pops or Rockiedog2 who recently mentioned looking at every part and the opportunity to save weight, and I'm all about that approach.


Input appreciated.
