As for the pre galvanized posts, you will need to grind of the galvanizing every where you weld or it gets nasty for fumes.
I do think 0.1" is about a perfect compromise between strength and weight.
We want 'em strong but the main point of a teardrop for me is light weight.
I don't like to go much thinner with galvanised steel. You can get a bit of hydrogen embrittlement from the pickling when they dip the steel.
I did think twice about keeping my single leaf galvanised springs, but since they are from Alko, I figured the production process would be up to scratch.
I have Alko galvanised springs on my boat trailer that haven't let me down, and it must be twenty years since I installed them.
I do know about zinc fumes, depending what I'm doing I grind it off or just set a fan up.
