Honestly that sounds like a terrible idea to me. Mixing copper and steel in a strap setup would probably make galvanic corrosion worse, not better, because those two metals are way apart on the galvanic scale. You'd basically be creating a battery effect right at the fasteners, which is the exact opposite of what you want. The copper would act as a cathode and the steel would corrode faster to protect it, so your straps would rot out even quicker. If anything, you should be matching metals or using insulators, not throwing copper into the mix. Tbh, I'd stick with all steel or use stainless if you're worried about corrosion, not start playing mad scientist with copper straps.

Started dating someone because we both delete more than we write.

Man I used to think the whole settling thing was just a myth contractors made up to upsell people. My house is a 1965 mid-century in the North Valley and I had the exact same experience, it was like 5 inches up there when I finally checked after my bills went insane. Added some blown-in fiberglass myself last fall for like $200 and saw a $30 drop in my Dec bill, so it definitely made a difference. Crazy how much that old insulation just packs down over 50 years and you don't even realize it.

Never slipped once" is what really got me because that's exactly the kind of thing that makes you switch sides in your head. I had the same thing happen with a different brand of tool a few years back and it felt like I was just being stubborn for no reason. It's humbling when your whole opinion gets flipped by actually using something instead of just going by what you heard. I think we all have that one brand we refuse to try until something forces us to. Good for you for giving it a real shot, that's more than most people do.

Oh man, that is a good point and honestly kind of a bummer if you're dealing with mostly uncompressed stuff like video or already compressed archives. I've definitely been burned by that before, thinking I was getting blazing speeds only to realize my file types were killing the compression ratio. It makes the whole "300MB/s" marketing number feel a little misleading when your actual workflow is just a bunch of mp4s or zips. Feels like you really gotta look at your specific data before getting too excited about those top-line specs. It's one of those things that sounds amazing on paper but reality can be a real buzzkill.
